摘要： A weatherseal or belt-line seal for a vehicle is formed by extrusion of an olefin-based thermoplastic elastomer or vulcanizate (first TPV) as an elongate body of arbitrary length and cross-section. The cross-section is adapted for use in a particular location in the opening of a structure to be protected against wind and rain, for example around the glass of a window in a vehicle's door, or around the opening (at the periphery) in which the door is closed, so as to present at least one sealing surface against which the glass or door may be abutted to provide a seal against the elements. A slip-coating is co-extruded onto one or more longitudinal sealing surfaces of the body; the slip-coating contains a novel compatibilizer which allows thermoplastic polyurethane (TPU) to be chemically bonded to a graft copolymer of polypropylene (PP) and a compound having two anhydride groups. The reaction product of the grafted PP and the TPU effects a thermal bond with the sealing surface of the body. The slip-coating has a combination of softness and abrasion resistance which are uniquely suited for the purpose of the weatherseal.

摘要： A thermoplastic elastomer is formed from a thermoplastic polymer such as a polyester, polycarbonate, or combinations thereof or a polyamide, which polymer is melt blended with an acrylic rubber. The acrylic rubber desirably has from about 0.5 to about 5 mole percent repeat units from halogen (desirably chlorine) containing monomer. Subsequently the acrylic rubber is crosslinked with 2,5-mercapto-1,3,4-thiadiazole or a derivative thereof. Such a thermoplastic elastomer may have a compression set less than 50% making it useful in applications involving continuous use under compression.
