ETHYLENE-ALFA-OLEFIN COPOLYMER RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain the subject resin composition excellent in transparency and resistance to weather by formulating a metal salt of cyclic organic phosphoric ester and an alkali metal compound to a specific ethylene-α-olefinic copolymer. SOLUTION: This copolymer resin composition is prepared by formulating (B) 0.01-5 pts.wt. of a metal salt of cyclic organic phosphoric ester of formula I [R1 is H, a 1-4C alkyl; R2 and R3 are each H, a 1-12C alkyl, an aryl; M is a metal in groups Ill and IV of the periodic table; X is -OH in the case that M is a metal in group III or 0=, (HO)2 - in the case that M is a metal in group IV] and (C) 0.005-5 pts.wt. of an alkali metal carboxylate, an alkali metalβ- diketonate, an alkali metalβ-ketoacetate and an alkali metal compound selected from the group of metal-modified hydrotalcite of formula II (M is an alkali metal; 0 .
