    • 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.
    • 通过加入0.005至5重量%的具有式“IMAGE”的苯基磷酸酯化合物的烯烃聚合物,其中R 1和R 2独立地选自氢原子, 具有1至18个碳原子的烷基,具有1至18个碳原子的烷氧基,具有5至12个碳原子的环烷基,苯基,苯氧基和其中R 5是氢原子的基团 或具有1至18个碳原子的烷基; R3选自具有1至18个碳原子的烷基,< IMAGE>和R4; R4是氢原子或金属原子当量M1 / a,其中a是金属原子M的化合价。在这种磷酸苯酯的存在下,通过还掺入某些金属化合物可以进一步提高透明度。
