Recycled polymer compositions and methods thereof

A method can include processing a cross-linked polymer and a catalyst during a melt processing operation to form a glass-like polymer, the cross-linked polymer comprising at least one monomer selected from the group consisting of vinyl esters, C2-C12 olefins, and combinations thereof. A method can include mixing a cross-linked polymer, a catalyst, and a non-cross-linked polymer at a temperature above a processing temperature of the non-cross-linked polymer to form a polymer composition; wherein the cross-linked polymer and the non-cross-linked polymer each comprise at least one monomer selected from the group consisting of vinyl esters, C2-C12 olefins, and combinations thereof, and wherein the cross-linked polymer is present in an amount of at least 15 wt% relative to the sum of the cross-linked polymer and the non-cross-linked polymer. 一种方法可以包括在熔融加工操作期间对交联聚合物和催化剂进行加工以形成类玻璃高分子，交联聚合物包含选自乙烯基酯、C2-C12烯烃及其组合的至少一种单体。一种方法可以包括在高于非交联聚合物的加工温度的温度下混合交联聚合物、催化剂和该非交联聚合物以形成聚合物组合物；其中，交联聚合物和非交联聚合物各自包含选自乙烯基酯、C2-C12烯烃及其组合的至少一种单体
