Graft-modified ultrahigh-molecular-weight polyethylene and process for producing same |
摘要 |
A graft-modified ultrahigh-molecular-weight polyethylene obtained by grafting (A) an ultrahigh-molecular-weight polyethylene having an inherent viscosity [ eta ], determined at 135 DEG C. in decalin, of at least 5 dl/g with (C) an unsaturated carboxylic acid graft-copolymerizable therewith or its graft-copolymerizable derivative, under melt-kneading condition in the presence of (B) an aliphatic compound having a melting point, determined by the DSC method, of at least 10 DEG C. and a boiling point of at least 130 DEG C., an amount of the component (C) grafted in said graft-modified ultrahigh-molecular-weight polyethylene being 0.01 to 10% by weight, and said graft-modified ultrahigh-molecular-weight polyethylene being substantially free of an insoluble gel product and having a tensile strength of at least 1.0 GPa; and a process for producing the same.
