The present disclosure provides embodiments of a quadripolymer composition. In an embodiment, a quadripolymer composition may have the formula E/P/X/CO, which may include from 25% to 90% by weight of ethylene (E), from 0.1% to 5.0% by weight of propylene (P), from 5% to 40% by weight of alkyl acrylate (X), and from 3% to 30% by weight of carbon monoxide (CO). X may be selected from the group consisting of vinyl acetate or n-butyl acrylate. The quadripolymer composition can have a melt index I2 of from 10 g/10 min to 1,000 g/10 min when measured at 2.16 kg and 190 DEG C according to ASTM 1238. In addition, the present disclosure provides embodiments of polymer formulations comprising the quadripolymer composition and polyvinyl chloride. 本公开提供了四元共聚物组合物的实施方案。在实施方案中，四元共聚物组合物可具有式E/P/X/CO，该四元共聚物组合物可包含25重量％至90重量％的乙烯(E)、0.1重量％至5.0重量％的丙烯(P)、5重量％至40重量％的丙烯酸烷基酯(X)和3重量％至30重量％的一氧化碳(CO)。X可选自由乙酸乙烯酯或丙烯酸正丁酯构成的组。当根据ASTM 1238在2.16kg和190℃下测量时，该四元共聚物组合物可具有10g/10min至1,000g/10min的熔体指数I2。另外，本公开提供了包含该四元共聚物组合物和聚氯乙烯的聚合物配制物的实施方案。
