摘要： This disclosure in certain embodiments relates to thermoplastic sheet compositions and applications incorporating such materials. More specifically this disclosure addresses thermoplastic sheets comprising: a) from 5 to 98.5 wt % of an essentially uncross-linked, random ethylene copolymer having from 20 wt % to 90 wt % repeat units from ethylene and from 10 wt % to 80 wt % of repeat units from one or more other ethylenically unsaturated monomers based upon the weight of the random ethylene copolymer; b) from 0.3 to 83.5 wt % of a polypropylene-based thermoplastic; and c) from 0.3 to 24.5 wt % of a vulcanized rubber dispersed phase. The disclosure also relates to methods of making the sheet compositions. One method includes incorporating a thermoplastic vulcanizate to provide the c) vulcanized rubber and in come cases, to supplement the b) polypropylene thermoplastic. Another method relates to melt blending polymer blends in appropriate proportions in the presence of a curing agent to effect dynamic vulcanization of a cross-linkable rubber component. Improved welding characteristics and weld strength of the sheets and reduced blocking in the extrusion step of producing the sheets is achieved.
