Title:
PRODUCTION OF POLYOLEFIN-POLYESTER GRAFT COPOLYMER
Document Type and Number:
Japanese Patent JPH05230191
Kind Code:
A
Abstract:
PURPOSE:To simply and efficiently obtain a polyolefin-polyester graft copolymer without causing gelatinization by reacting a specific polyester with a polyolefin. CONSTITUTION:(A) A polyester containing 10-2,000 milliequivalent phenolic hydroxyl group and/or amino group in the main chain of molecule and <=10ppm antimony content is blended in a molten state and reacted with (B) with a polyolefin containing epoxy in the molecule at 150-300 deg.C to give the objective copolymer.
