Title:
POLYCARBONATE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/215424
Kind Code:
A1
Abstract:
The present invention relates to polycarbonate, a preparation method therefor and an application thereof. The method comprises preparing a ureidopyrimidinone type diisocyanate from a first compound and a second compound; and reacting a third compound with the prepared ureidopyrimidinone type diisocyanate to obtain the polycarbonate. Using the polycarbonate in place of a scratch-resistant metal material can alleviate the defects of signal blocking, high weight, and ready generation of static electricity in winter associated with the scratch-resistant metal material, and the material has self-healing properties. A housing prepared from the polycarbonate has good thermal resistance, and thus internal components can be well protected.
