METHOD OF PREPARING MONOMER-GRAFTED SYNDIOTACTIC POLYSTYRENE WITH POLARITY

摘要

The present invention provides a method of preparing a monomer-grafted syndiotactic polystyrene with polarity, which comprises (a) forming swollen syndiotactic polystyrene by mixing with a syndiotactic polystyrene in powder state and a radical initiator in a solvent at the temperature of 40-80° C. using a batch reactor, and (b) grafting a monomer selected from the group consisting of maleic anhydride, maleic imide and derivatives thereof onto the swollen syndiotactic polystyrene.
