Title:
COMPATIBILIZING AGENT AND POLYOLEFIN-BASED POLYMER ALLOY
Document Type and Number:
Japanese Patent JPH05345828
Kind Code:
A
Abstract:
PURPOSE:To obtain a new compatibilizing agent having excellent compatibility to polyolefin resins and phenolic resins and useful for the production of a polyolefin polymer alloy having excellent flame-retardance by reacting two specific kinds of resins in melt state. CONSTITUTION:This compatibilizing agent is produced by the melt reaction of a composition consisting of (A) 90-10wt.% of a resin selected from a modified polyethylene containing carboxylic acid anhydride group (e.g. ethylene.acrylic acid copolymer) and a carboxylic acid-modified product of a hydrogenated block copolymer obtained by the hydrogenation of a block copolymer consisting of a polymer block composed mainly of a vinyl aromatic compound and a polymer block composed mainly of a conjugated diene compound (e.g. maleic anhydride-modified styrene-ethylene.butylene-styrene block copolymer) and (B) 10-90wt.% of a phenolic resin (preferably novolac phenolic resin or a solid resol resin produced by using ammonia as the catalyst). The melt reaction is preferably carried out at 180-220 deg.C for 5-30min using a pressure kneader, etc.
