Poly(viaylidene fluoride) [24937-79-9] is the addition polymer of 1,1-difluoroethene [73-38-7], commonly known as vinylidene fluoride and abbreviated VDF or VF2. The formula of the repeat unit in the polymer is —CH2—CF2—. The preferred acronym for the polymer is PVDF, but the abbreviation PVF2 is also frequently used. The history and development of poly(vinyhdene fluoride) technology has been reviewed (1 3). 

Recent work on thermoplastic vulcanizates (TPVs) will not be included in this chapter since it is being reviewed elsewhere in the book. Abbreviations for some mbbers and accelerators will be used throughout in place of their full names as shown in Table 11.1. Acronyms for other polymers and additives wUl be provided in the text as required. A short discussion of polymer miscibility and compatibUization of polymer blends will be provided for better appreciation of the subject. 

In the following discussion, block copolymers will be simply designated by the acronym A-B for a diblock copolymer, A-B-A for a triblock copolymer with two identical outer blocks, A-B-C for an ABC triblock copolymer, etc. A complete list of abbreviations for the A, B, and C polymer blocks is given in the Abbreviations and Symbols section. 

Acronyms and abbreviations are not used to confuse the student nor to save printing space, but rather because it is often industrial practice to employ these abbreviations. Thus it is to the reader s advantage to do likewise. A fuller listing appears in Polymer News 9 (4), 101-110 0983). 

PPG [Polypropylene Glycol] Abbreviated to the acronym PPG by the International Nomenclature Cosmetic Ingredient. Polypropylene glycol polymers are named as PPG-x , where x is the average number of propylene oxide (CjHgO) monomer units (e.g., PPG-10). Esters and ethers of polypropylene glycol polymers are named as PPG derivatives (e.g., PPG-10 stearate, PPG-10 lauryl ether). These compounds are generally used as emollients, emulsifiers, humectants, or surfactants. 

A glossary of the symbols, acronyms and other abbreviations used, a table of the molecular weights of the repeat units of a large number of polymers, and an extensive subject index, will be provided at the end of the book. 

Tables 1.2 - 1.5 contain a compilation of the plastics discussed in this volume, their chemical abbreviations, and some selected trade names. An extensive table of polymer acronyms on ASTM, DIN, and ISO standards can be found in Appendix 9.4.

Structural note regarding fluoropolymers In Tables 59.1 and 59.3 Rigorous application of nomenclature rules can lead to fluoropolymer names of excessive length for tabulations. There are few generally agreed abbreviations or acronyms for such polymers so rather than add to this problem we have dropped precise descriptions of substituent positions in the names in the tables. To avoid any confusion, the full names of these polymers are given below ...

These building blocks can be combined into nets (or networks) where the net, whether 1-, 2- or 3-dimensional, is sometimes called a coordination polymer if it is held together by metal-ligand or coordination bonds. For the 3D-case, metal-organic frameworks can be used. The acronym MOF for metal-organic framework should be avoided since the parent term is not yet well established and there seem to be no great need for an abbreviation in the context where it is used.

Within the field of ionic polymerisation a number of specialized reviews have appeared. As an example the preparation of polymers bearing zwitterionic end groups has been reviewed [1]. In the field of polymer synthesis there is a strong tradition to use acronyms as a shorthand notation for chemical species. Apart from saving space this practice makes a text more readable for the well-informed reader. However, this benefit is achieved at the cost of the texts being unapproachable for the less-informed reader. This fact has prompted the inclusion in this chapter of an extensive list of acronyms that are used in the text and where the commonly used forms of abbreviation are maintained such... 

Abbreviations and acronyms are also extensively used in the chemical literature for monomers, polymers, as well as for additives, modifiers, and fillers. Their extensive list is provided in Section Vlll of this Handbook. 

As is clearly stated there, the same abbreviation is often used for different monomers and polymers, and the same polymer may have different abbreviations or acronyms. 

Abbreviations and acronyms for the names of thermoplastics, thermosets, fibers, elastomers, and additives have been proposed by many national and international organizations. Some of these abbreviations were introduced by law, others are trademarks in eertain eountries. As a result, the same abbreviation is often used for different polymers. The same polymer may also have different abbreviations or aeronyms. Furthermore, some abbreviations refer to ehemieal compounds (lUPAC) whereas abbreviations leeommended by ASTM, BS, DIN, and ISO usually refer to plastics, fibers, elastomers, etc., that are based on the corresponding polymers, i.e., polymers plus additives, modifiers, fillers, ete. 

Section B lists, in alphabetical order, the abbreviations and acronyms for thermoplastics, thermosets, fibers, elastomers, and additives. Sections C and D list the abbreviations for polymers, based on their monomeric imits and characteristic groups, respectively. Section E contains abbreviations and acronyms for polymers obtained by chemical transformation of base polymers. Section F contains special abbreviations for blends, reinforced polymers, etc., and Section G the ISO and DIN codes for plastics. Section H lists the special abbreviations connected with the recycling of plastics. Recommended abbreviations and acronyms for elastomers and fibers are given in Sections I and J, respectively. 

The following table contains the abbreviations and acronyms of names of polymeric materials whose base polymers were obtained by chain polymerization (addition polymerization), copolymerization, polycondensation (condensation polymerization), and polyaddition. Note that these abbreviations and acronyms do not apply in industry to polymers per se but to polymeric materials, i.e. polymers with or without additives, tillers, plasticizers, etc. 

Abbreviations and acronyms are in part based on the poly(monomer) nomenclature, i.e., on the names of the monomers used in the manufacture of polymers, sometimes however, without a prefix P for poly . The names of monomers for copolymers are given in alphabetical order without regard to their prevalence.
