ABSTRACT:
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.
