Title:
PROCESSABLE OPAQUE HIGH-IMPACT MBS FOR PVC, AND METHOD FOR PROCESSING SAME
Document Type and Number:
WIPO Patent Application WO/2020/164302
Kind Code:
A1
Abstract:
Disclosed are processable opaque high-impact MBS for PVC, and a method for preparing same, which relate to the technical field of PVC additive manufacturing and preparation. The processable opaque high-impact MBS for PVC has a three-layer structure of core-nucleus-shell, and is composed of components with the following mass fractions: 1%-20% core layer structure, 70%-85% nucleus layer structure, and 5%-20% shell layer structure, wherein the core layer structure is a semi-rigid slightly cross-linked copolymer of a styrene monomer and an acrylate monomer; the nucleus layer structure is a relatively soft and slightly cross-linked butadiene styrene polymer with a relatively low glass transition temperature; and the shell layer structure is a copolymer with a relatively high glass transition temperature of styrene, butyl acrylate and methyl methacrylate. The problems, such as low impact strength and poor processing fluidity, with an existing MBS product for an opaque PVC product are solved.
