ABSTRACT:
A resin composition of propylene-ethylene random copolymer comprising (a) a propylene-ethylene random copolymer, (b) at least one alkali salt selected from the group consisting of alkali carboxylates, alkali .beta.-diketonates and alkali salts of .beta.-ketacetate, (c) an organophosphoric compound, and (d) a lithium aluminum compound. The organophosphoric compound is represented by the following formula (I): ##STR1## wherein R.sub.1 is hydrogen or an alkyl group having 1 to 4 carbon atoms, each of R.sub.2 and R.sub.3 is independently hydrogen or an alkyl group having 1 to 12 carbon atoms, M is a metal atom of an element selected from the group consisting of Group III, IV, XIII and XIV elements of the Periodic Table, and X is --OH when M is a metal atom of an element of Group III or XIII of the Periodic Table or X is .dbd.O or (--OH).sub.2 when M is a metal atom of an element of Group IV or XIV of the Periodic Table, and the lithium aluminum compound is represented by the following formula (II):
wherein Y is an inorganic or organic anion, n is a charge of Y and m is a number of 3 or less.
