In polymer chemistry, a copolymer is a polymer derived from more than one species of monomer. The polymerization of monomers into copolymers is called copolymerization. Copolymers obtained from the copolymerization of two monomer species are sometimes called bipolymers. Those obtained from … See more 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, See more Block copolymers can "microphase separate" to form periodic nanostructures, such as styrene-butadiene-styrene block copolymer. The polymer is known as Kraton and is used for shoe soles and adhesives. Owing to the microfine structure, … See more Block copolymers A common application of block copolymers is to develop thermoplastic elastomers (TPEs). … See more Block copolymers Block copolymers comprise two or more homopolymer subunits linked by covalent bonds. The union of … See more There are a variety of architectures possible for nonlinear copolymers. Beyond grafted and star polymers discussed below, other common types of branched copolymers include brush copolymers and comb copolymers. Graft copolymers See more Characterization techniques for copolymers are similar to those for other polymeric materials.
