| abstract | The present invention discloses a block copolymer comprising a block with glass transition temperature higher than 100° C. and a method for preparing the same. In the method, latex of a block copolymer is prepared by taking n-butyl acrylate as a soft block, random copolymer of styrene and γ-methyl-α-methylene-γ-butyrolactone as a hard block, utilizing emulsion polymerization system and reversible addition fragmentation chain transfer radical polymerization technology. The method utilizes an amphiphilic macromolecule reversible addition fragmentation chain transfer agent has dual function of both chain transfer agent and emulsifier, thus can achieve good control of monomer polymerization and avoid the use of traditional emulsifier; the reaction has no polymerization inhibition period, has fast reaction rate and high final conversion; colloidal particles can stably grow; product has a hard block with glass transition temperature up to 155° C., and thus has a good application prospect in the field of high heat resistance thermoplastic elastomer. |
