NOVEL THERMOPLASTIC POLYHYDROXY POLYETHER RESIN AND RESIN COMPOSITION CONTAINING THE SAME

摘要

Disclosed is a novel flame-retardant thermoplastic polyhydroxy polyether resin obtained by reacting at least one epoxy resin (A) selected from glycidyl esters of a divalent aliphatic carboxylic acid having 15-64 carbon atoms and glycidyl ethers of a divalent aliphatic alcohol having 15-64 carbon atoms and a phosphorus atom-containing divalent phenol compound (B) as essential components. This flame-retardant thermoplastic polyhydroxy polyether resin contains 2-52% by mole of the component (A) relative to the total resin, while having a weight average molecular weight of 10,000-200,000 and a phosphorus content of 1-5% by weight.
