Title:
PRODUCTION OF CROSSLINKABLE POLYSTYRENE HAVING AFFINITY TO WATER AND ALCOHOL
Document Type and Number:
Japanese Patent JPS62124103
Kind Code:
A
Abstract:

PURPOSE: To easily produce the titled polymer at room temperature, by reacting a styrene-maleic anhydride copolymer with a mono-, di- or trialcohol amine and reacting the reaction product with a polyethylene oxide diamine.

CONSTITUTION: The objective polymer can be produced usually as a three- dimensionally crosslinked insoluble and infusible film by reacting (A) a part of an acid anhydride composition in a styrene-maleic anhydride copolymer (preferably having a molecular weight of ≥100,000) [preferably ≥5.5(mol)% of the acid anhydride composition to decrease the residual acid anhydride in the composition to ≤5.5%] with (B) a mono-, di- or trialcohol amine [preferably the compound of formula (n is 2W5)] in an organic solvent such as CHCl3 and reacting the reaction product with (C) a polyethylene oxide diamine at room temperature.
