Abstract
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.
Claims11
A method for preparing a modified syndiotactic polystyrene with polarity, comprising the steps of:
- (a) providing swollen syndiotactic polystyrene by mixing syndiotactic polystyrene in the form of powder with a radical initiator in organic solvent in a batch reactor;
- and
- (b) graft-polymerizing the swollen syndiotactic polystyrene with a monomer having a polar group.
