WebReactivity ratios. The reactivity ratio of a growing copolymer chain terminating in a given monomer is the ratio of the reaction rate constant for addition of the same monomer and the rate constant for addition of the other monomer. That is, = and =, where for example is the rate constant for propagation of a polymer chain ending in monomer 1 (or A) by addition … WebA homopolymer plastic is one that is produced by the polymerization of a single monomer. For example, polystyrene is composed of nothing but styrene monomer residues, making it a homopolymer.

The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. There is in fact a hierarchy of structures, in which each stage provides the foundations for the next one. The starting point for the description of the structure of a polymer is the identity of its constituent monomers. Next, the microstructure essentially de… WebThe polymers which have only one type of repeating unit are called homopolymers. They are formed from a single monomer. In certain cases, the repeating unit is formed by the … WebExamples. Polyvinyl acetate, Polyethylene oxide, etc. Conclusion. The above discussion concludes that homopolymer and copolymer both are types of macromolecules. Homopolymer is the polymer made up of one kind of repeating unit, whereas the copolymer is made up of two different kinds of repeating units. list of breweries in scotland
