WebIn chemistry terms the difference between copolymer and comonomer is that copolymer is a polymer derived from more than one species of monomer while comonomer is any of … Monomers can be classified in many ways. They can be subdivided into two classes, depending on the kind of the polymer that they form. Monomers that participate in condensation polymerization have a different stoichiometry than monomers that participate in addition polymerization: Other classifications include:
WebIn polymer chemistry, a comonomer refers to a polymerizable precursor to a copolymer aside from the principal monomer. In some cases, only small amounts of a comonomer … WebMay 7, 2024 · When the reactivity ratios of comonomer pairs are similar, random copolymerizations are observed. Ethylene with a reactivity ratio of r1=0.79 and VAM (r2=1.4) copolymerizes well, affording alternating copolymer compositions closely reflecting the compositions of the monomer feeds. When the reactivity ratios of two monomers differ …
