Process for the production of thermoplastic polyvinylchloride molding material and use thereof |
摘要 |
<p>The process for the production of thermoplastic polyvinyl chloride molding compositions comprises modification with a core-shell modifier comprising a polyvinyl chloride or vinyl chloride copolymer core and a cross-linked alkyl acrylate- or alkylmethacrylate homo- or copolymer shell and the graft polymerization of the vinyl chloride monomer is carried out in the presence of the toughening agent. A process for the production of thermoplastic polyvinyl chloride molding compositions in first step modified with an elastomer containing a core-shell modifier in second step, having improved impact and corner strength and improved surface gloss is characterized such that the core of the toughening agent comprises polyvinyl chloride or vinyl chloride copolymer and the shell comprises cross-linked alkyl acrylate- or alkylmethacrylate homo- or copolymers and the graft polymerization of the vinyl chloride monomer is carried out using a suspension process in the presence of the toughening agent. It is described further the use of the molding material in plastic sections intended particularly for the production of window frames and pipes.</p> |
