Problems solved by technology

However, in this method, it is necessary to adopt a special and complicated process method, for example, the matrix resin monomer and the modified resin monomer are polymerized at the same time, or one of these monomers is preliminarily polymerized into a certain extent, followed by polymerization of the two components or chemical reactions using functional groups
[0005] Specifically, in the current art, no known technical method has been reported for the formation of thermoplastic interpenetrating network structures by a convenient technique using a relatively small amount of modified resin without relying on polymerization or chemical reactions between the components

Abstract

The invention relates to a thermoplastic high-molecular composition interpenetrated network structure and a preparation method thereof. More particularly, the invention relates to the thermoplastic high-molecular composition interpenetrated network structure obtained by adopting a supercritical process to process a thermoplastic high-molecular composition.

Description

technical field [0001] The invention relates to an interpenetrating network structure of a thermoplastic polymer composition and a preparation method thereof. More specifically, the present invention relates to an interpenetrating network structure of thermoplastic polymer composition obtained by using supercritical technology to process thermoplastic polymer composition. Background technique [0002] A modified polymer composition is usually obtained by adding other materials to the matrix resin. Representative examples of other materials may include thermoplastic elastomers (hereinafter referred to as "modified resins") for improving impact resistance and chemical resistance different from the base resin, fillers and additives for reinforcing materials, and the like. As for the mixing method, conventionally developed various techniques such as compatibilization, dynamic vulcanization, and reactive extrusion, etc. can be used. [0003] In the common method of adding modif...
