| titleOfInvention | Block copolymer containing block with glass transition temperature higher than 100°c and method of production thereof |
| abstract | Disclosed are a block copolymer containing a block with the glass transition temperature higher than 100°C and a method for preparing the block copolymer. In the method, the block copolymer latex is prepared by taking n-butyl acrylate as a soft segment and the random copolymer of styrene and gamma-methyl-alpha-methylene-gamma-butyrolactone as a hard segment, adopting an emulsion polymerization system and applying a reversible addition-fragmentation chain transfer free radical polymerization technology. The method adopts simple processes and equipment, and the processes are environmental-friendly and energy-saving; an amphipathic macromolecule reversible addition-fragmentation chain transfer reagent is adopted, has the dual functions of both a chain transfer reagent and an emulsifier, not only is the good monomer polymerization control realized, but also the traditional emulsifier is prevented from being used; the reaction has no inhibition period, the reaction speed is high and the final conversion rate is high; the colloidal particles are stably increased during the process; and the glass transition temperature of the hard segment of the product can reach 155°C, and the block copolymer has a good application prospect in the field of high-heat-resistance thermoplastic elastomers. |
