Because the rules for organic nomenclature determine the priority of naming different carbon chains from their relative lengths, the systematic names for type AABB polyamides depend on the relative length of the carbon chains between the amide nitrogens and the two carbonyl functions of the polymer for aUphatic nylon-Ayy, when x < the lUPAC name is poly[imino-R imino(l2y-dioxo-R )]. When x > then the name is... [Pg.216]

Polymerization Solvent. Sulfolane can be used alone or in combination with a cosolvent as a polymerization solvent for polyureas, polysulfones, polysUoxanes, polyether polyols, polybenzimidazoles, polyphenylene ethers, poly(l,4-benzamide) (poly(imino-l,4-phenylenecarbonyl)), sUylated poly(amides), poly(arylene ether ketones), polythioamides, and poly(vinylnaphthalene/fumaronitrile) initiated by laser (134—144). Advantages of using sulfolane as a polymerization solvent include increased polymerization rate, ease of polymer purification, better solubilizing characteristics, and improved thermal stabUity. The increased polymerization rate has been attributed not only to an increase in the reaction temperature because of the higher boiling point of sulfolane, but also to a decrease in the activation energy of polymerization as a result of the contribution from the sulfonic group of the solvent. [Pg.70]

The structure of poly(iminocarbonates) synthesized by the direct interfacial polymerization of BPA and cyanogen bromide was analyzed by NMR, Fourier transform infrared spectroscopy and elemental analysis and found to be identical in all aspects to authentic poly(imino-carbonates) obtained by solution polymerization (46). [Pg.218]

Successive multiple insertions of an aryl isocyanide (ArNC) into the S-S bond of a diaryl disulfide (ArS)2 occurs in the presence of Pd(PPh3)4 to produce the corresponding poly(imino)alkane endcapped with an arylthio group (Equation (65)).167 Products of higher molecular weights are formed when isolated poly(imino)alkanes are again subjected to the conditions of the insertion reaction (up to n — 9). [Pg.752]

Poly(imino-l,4-phenyleneiminoterephthaloyl) (XIV) (trade names Kevlar, Twaron) is synthesized from the corresponding para-substituted diamine and diacid chloride. Poly (iminocarbonyl-l,4-phenylene) (XV) (also known as Kevlar) is based on p-aminobenzoic acid. [Pg.100]

Not used in Chemical Abstracts, but appear in other references, eg, Ref. 3. k In poly[imino(l-oxo-R)], poly[imino-R iminofl y-dioxo-R")], and poly[imino-(l dioxo-R )imino-R ], as explained in text. Polymers based on carbonic acid and diamines are considered polyureas. [Pg.216]

Examples of the two macromolecular nomenclature systems are as follows. For source-based names for homopolymers and copolymers polyacrylonitrile, poly(mcthyl methacrylate), polylacrylamidc-co-vinylpynolidinone), polybutadiene-felocJ-polystyrene, and poly(propyl methacrylate)-gra/t-poly( 1-vinylnaphthalene). Structure-based examples arc as follows polyloxy-l,4-phcnylcnct (1), po]y(oxycthyl-cncoxytcrcph-thaloy) (2) and poly[imino(l-oxo-l,6-hexanediyl)J (3). [Pg.1091]

Photocatalytically active polymer having acridine units in the backbone was synthesized by the polycondensation of 3,6-diaminoacridine (proflavine) as a diamine and m-dibromobenzene (Scheme 13) [68]. Mullen and coworkers synthesized a series of novel poly(imino ketone)s via Pd-catalyzed polycondensation of aromatic dichloro or dibromo ketones with various aromatic diamines (Scheme 14) [69]. The Mw values were in the range of 19500-474 500. The FT-IR spectra of the obtained polymer revealed that in the solid state intermolecular and intramolecular hydrogen bonding (N-H 0=C)... [Pg.12]

Isonitrile is isoelectronic with CO, and iminoacyl complexes can be compared with acyl ones. The most remarkable difference is that isonitrile undergoes multiple insertion, not observed in CO, into transition-mctal-carbon bonds to produce bis-, tris- or poly(imino) complexes . ... [Pg.265]

Although there are clear lUPAC rules for naming the polymers, in practice various names for the same polymer are frequently encountered. As an example, a simple polymer such as nylon 6 (commercial name) can be named poly(e-caprolactam), poly[imino(1-0X0-1,6-hexandiyl)], poly(6-aminohexanoic acid), polycaproamide or poly(pentamethylenecarbonamide). [Pg.10]

Besides scientific names, many polymers are indicated by their common name, trade name, brand name, or abbreviation (commercial names) [4]. Typical examples of common names are nylon or silicone. Several nylons are known and the name nylon 6 is used for poly[imino(1-oxo-1,6-hexandiyl)], the name nylon 66 is used for poly(iminohexa-methyleneiminoadipolyl), etc. Trade names such as Teflon for poly(tetrafluoro-ethylene) made by DuPont, Nomex for poly(iminoisophthaloylimino-1,3-phenylene), or Kevlar for poly(iminoisophthaloylimino-1,4-phenylene) are also common. Many abbreviations are in use for both homopolymers and copolymers. Table 1.2.1 gives some of the common abbreviations for polymers. [Pg.10]

Besides the aliphatic and aliphatic/aromatic nylons, aromatic polyamides have excellent capability to form fibers. Among aromatic polyamides the most common are Kevlar or poly(imino-1,4-phenyleneiminocarbonyl-1,4-phenylenecarbonyl) or poly(phenylene terephthalimide), and Nomex or poly(phenylene isophthalimide). These compounds are included in a group of polyamides known as aramids. The structures of Kevlar and Nomex are shown below ... [Pg.595]
