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 three and four monomers are called terpolymers and quaterpolymers, respectively. … WebThe yield of graft copolymer refers to the amount of copolymer obtained in the grafting reaction. It was calculated according to the following equation (Ke et al. 2010), Yield of graft copolymer (%) (1) where w 0, w 1 and w 2 are the weight of crude EHL, DA and graft copolymer DA-g-EHL, respectively. The increase of acid value was defined as ...
