Abstract:
1. A polymer composition comprising: a polymer having a main polymer chain derived from: (i) at least about 30% by weight of a first monomer which introduces at least one of a secondary carbon and a tertiary carbon to the main polymer chain, and (ii) from 0 to about 70% by weight of a second monomer; and a salt of a strong base and a weak acid, the salt comprising a metal selected from Group I of the Periodic Table of Elements, wherein the polymer main chain consists of an elastomer copolymer consisting of ethylene and propylene, wherein the salt of a strong base and a weak acid is selected from the group consisting of potassium carbonate, sodium carbonate, sodium or potassium salts of C wherein the salt is present in the polymer composition in an amount in the range of from about 2.5 to about 7.5 parts based on phr.
