Problems solved by technology

This kind of toughening method has achieved great success in industry, but there are still insurmountable problems, such as the stiffness, strength, and heat distortion temperature have been greatly reduced.
Typically, for example, the notched Izod impact strength of high-impact polystyrene (HIPS) is 4.5 times that of polystyrene (PS), but the tensile modulus is only 46% of polystyrene (PS)

Abstract

An elastomer and organic rigid particle co-operating toughened polyphenylacetylene and a corresponding preparation method belong to macromolecule material technical field, in particular to a toughened polyphenylacetylene prepared by fusing and blending polyphenylacetylene and co-operating components and a corresponding preparation method, wherein the co-operating components are polybutadiene rubber (PB) elastomer and organic rigid particles (PSDM) which is polymerized from phenylethene (St), divinylbenzene (DVB) and divinylbenzene (MMA) via emulsion. The inventive toughened polyphenylacetylene, compared with pure polyphenylacetylene, at basic tension strength has better impact strength, with wide application in plastic industry.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a toughened polystyrene and a preparation method thereof. Background technique [0002] Polystyrene plastic has the advantages of high rigidity, easy dyeing and easy processing and molding, and is widely used in electrical appliances, instrumentation, packaging and decoration, and daily life. However, polystyrene is a brittle plastic with low impact resistance, which limits its application in high impact products. For this reason, people have done a lot of work on polystyrene toughening modification for a long time, roughly experienced elastomer blending modification, thermoplastic resin blending modification, inorganic nanoparticles blending modification and organic rigid particle modification four stages. The following will make an introduction respectively: [0003] (1) Elastomer blending modification [0004] As early as the 1920s, according to the method of usi...
