    摘要： The clarity of molded olefin polymer specimens is augmented by incorporating 0.005 to 5% by weight of the olefin polymer of a phenyl phosphate compound having the formula ##STR1## in which R.sub.1 and R.sub.2 are independently selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, an alkoxy group having 1 to 18 carbon atoms, a cycloalkyl group having 5 to 12 carbon atoms, a phenyl group, a phenoxy group, and a group ##STR2## in which R.sub.5 is a hydrogen atom or an alkyl group having 1 to 18 carbon atoms; R.sub.3 is selected from the group consisting of an alkyl group having 1 to 18 carbon atoms, ##STR3## , and R.sub.4 ; and R.sub.4 is a hydrogen atom or a metal atom equivalent M.sub.1/a where a is the valence of the metal atom M.In the presence of such a phenyl phosphate, further improvements in clarity are obtained by also incorporating certain metal compounds.

    摘要： Light and heat stabilizers for synthetic resin compositions and synthetic resin compositions containing such stabilizers are provided, comprising(1) at least one hindered and heterocyclic amine having the formula: ##STR1## wherein: X is a bivalent linking radical forming with the ring structure ##STR2## a nitrogen-containing heterocyclic ring having from five to seven ring atoms, preferably piperidine;R.sub.1 and R.sub.2 are each selected from the group consisting of lower alkyl, preferably methyl, and R.sub.1 and R.sub.2 taken together as pentylene (CH.sub.2).sub.5 ;R.sub.3 and R.sub.4 are each selected from the group consisting of lower alkyl, and R.sub.3 and R.sub.4 taken together as one of butylene--(CH.sub.2).sub.4, pentylene--(CH.sub.2).sub.5, and CH.sub.2 --C(CH.sub.3).sub.2 --NH--C(CH.sub.3).sub.2 --CH.sub.2 --;n is 1 or 2; andwhen n is 1, Y is selected from the group consisting of hydrogen, O.degree., OH, alkyl, alkenyl, alkynyl, aralkyl and acyl having from one to about thirty carbon atoms; andwhen n is 2, Y is selected from the group consisting of alkylene, alkenylene, alkynylene, cycloalkylene and aralkylene having from one to about thirty carbon atoms; together with(2) at least one alkyl thioalkanoic acid amide having the formula: ##STR3## wherein: R is alkyl having from about four to about fifty carbon atoms;R' is alkylene having from one to about three carbon atoms;R.sub.8 is selected from the group consisting of hydrogen, alkyl and aryl having from about one to about eighteen carbon atoms; and when n is 2 and p is 0, bivalent alkylene and oxyalkylene linked to N at two positions;R.sub.9 is selected from the group consisting of alkylene, dialkylene, cycloalkylene, and arylene having from about one to about twelve carbon atoms; and isocyanurate;R.sub.10 is selected from the group consisting of alkylene, alkenylene, thiodialkylene and arylene having from about one to about eighteen carbon atoms;m is 1, 2 or 3;n.sub.1 and n.sub.2 are 0, 1 or 2;p, p.sub.1 and p.sub.2 are 0 or 1;and when p is 1, and n and m are each 1, the sum of m, n and p is three; andq.sub.1, q.sub.2 and q.sub.3 are each 0 or 1:In such combinations, the alkyl thioalkanoic acid amide synergizes the stabilizing effectiveness of the hindered heterocyclic amine.
