    摘要: A synthetic resin compatibilizer comprising a copolymer of a polyoxyalkylene derivative represented by general formula(I) with maleic anhydride, maleic acid, or a salt or an ester thereof ##STR1## where B represents a residue of a compound having from 2 to 8 hydroxyl groups; AO represents an oxyalkylene group having from 2 to 18 carbon atoms; R.sup.1 represents an unsaturated hydrocarbon group having from 2 to 5 carbon atoms; R.sup.2 represents a hydrocarbon or acyl group having from 1 to 40 carbon atoms; a is from 0 to 1,000; b is from 0 to 1,000; c is from 0 to 1,000; l is from 1 to 8; m is from 0 to 2; and n is from 0 to 7; l+m+n=2 to 8; al+bm+cn=1 to 1,000, and m/(l+n).ltoreq.1/3.The synthetic resin compatibilizer provides a polymer alloy having excellent tensile and flexural strengths.
