TERPOLYMER COMPOSITIONS WITH IMPROVED CLARITY AND GLOSS FOR BLOW MOLDED AND THERMOFORMED ARTICLES

摘要

A polymer composition and/or an article containing:
(a) a random propylene terpolymer which comprises:
(i) 90.0-96.0 wt. %, based on the total weight of the propylene terpolymer, of propylene derived units;(ii) 3.0-7.0 wt. %, based on the total weight of the propylene terpolymer, of 1-butene derived units; and(iii) 1.0-5.0 wt. %, based on the total weight of the propylene terpolymer, of ethylene derived units; and(b) about 0.01 to about 1.0 wt. %, based on the total weight of the propylene terpolymer, of a clarifying agent, with the balance of the polymer composition being the random propylene terpolymer and/or optionally at least one additive.
