ABSTRACT:
Methods of making ultrahigh molecular weight polyethylene (UMWPE) having increased strength and/or wear resistance, such as high yield strength, high tensile strength, high load strength, and/or high impact strength. Some embodiments include making UHMWPE having increased strength and/or wear resistance, such as that listed above, where the UHMWPE has co-monomers.
