Abstract

The present disclosure provides embodiments of a tetrapolymer composition. In embodiments, the tetrapolymer composition may have the formula E/P/X/CO, which may include from 25 wt. % to 90 wt. % of ethylene (E), from 0.1 wt. % to 5.0 wt. % of propylene (P), from 5 wt. % to 40 wt. % of alkyl acrylate (X), and from 3 wt. % to 30 wt. % of carbon monoxide (CO). X may be selected from the group consisting of vinyl acetate or n-butyl acrylate. The tetrapolymer composition may have a melt index, I2, from 10 to 1,000 g/10 min when measured according to ASTM 1238 at 2.16 kg and 190 C. Additionally, the present disclosure provides embodiments of a polymer formulation comprising the tetrapolymer composition and polyvinyl chloride.

Claims (22)
