Poly monomers

Other poly(monomer)s and allow for the representation of alternating bonds and confignration. 

Consistent notation is adopted throughout this book. Diblock copolymers are written poly(monomer A) poly (monomer B) or PA-PB, where examples of PA and PB are illustrated in Fig. 1.2. Similarly, triblock copolymers are written poly(monomer A)-poly(monomer B)-poly(monomer C) or PA-PB PC. Deuterated blocks are denoted dpoly(monomer A) or dPA. The molar mass of a copolymer is denoted by M, or Af corresponding to the weight- or number-average respectively, and the composition is specified by the volume fraction of one component,/. In solution, the volume fraction of a copolymer is denoted [Pg.3]

It is useful to digress at this point to review some common names for frequently used vinyl monomers. These are summarized in Fig. 1-4. Alternativenames will be apparent, but these are not used by convention. (Thus acrylonitrile could logically be called vinyl cyanide, but this would be an unhappy choice from a marketing point of view.) The polymer name in each case is poly monomer. ... 

For the common nomenclature the usual practice is to name a polymer according to its source, i.e., the monomer(s) used in its synthesis, and the generic term used is poly"monomer", whether or not the monomer is real. The prefix poly is added on to the name of the monomer to form... 

For the common nomenclature the usual practice is to name a polymer according to its source, i.e., the monomer(s) used in its synthesis, and the generic term used is poly monomer , whether or not the monomer is real. The prefix poly is added on to the name of the monomer to form a single word, e.g., polyethylene, polystyrene, and polyacrylonitrile (see Table 1.1). However, when the monomer has a multiworded name, the name of the monomer after the prefix poly is enclosed in parentheses, e.g., poly(vinyl chloride), poly(vinyl alcohol) and poly (methyl methacrylate) (Table 1.1).

For unspecified or unknown copolymers the name is poly(monomer 1-co-monomer 2). 

Most abbreviations are based on the form poly(monomer) , i.e. on the names of the monomers used in polymer synthesis, often with the prefix P for poly . In case of copolymers, the monomers are given in alphabetic order. Some abbreviations also catch structural features or physical properties. ...

Polymers are usually named according to their source, and the generic term is poly monomer whether or not the monomer is real. Thus we have polystyrene (1-1) and poly(vinyl alcohol) (1-7). Similarly, polyethylene is written as 1-3 although the representation -fCH2>2n and the corresponding name polymethylene could have been chosen equally well to reflect the nature of the repeating unit. 

In most copolymeiization, the monomers are consumed at different rates dictated by the steric and electronic properties of the reactants. Consequendy, both the monomer feed and copolymer composition will drift with conversion. Thus conventional copolymers are generally not homogeneous in composition at the molecular level. In RAFT polymerization processes, where all chains grow throughout the polymerization, the compositional drift is captured within the chain stmcture (Scheme 32). All chains will have similar composition and the copolymers formed have a gradient or tapered structure - poly(monomer A-grad-monomer B).

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.
