Document Type and Number:
WIPO Patent Application WO/2024/053274
Kind Code:
A1
Abstract:
The present invention provides a polycarbonate resin composition which has excellent tensile strength, wet heat resistance, chemical resistance and processability. A composition according to the present invention contains, relative to 100 parts by weight of (A) an aromatic polycarbonate resin (component A), 20 to 130 parts by weight of (B) glass fibers (component B), and 1 to 10 parts by weight of (C) a phenoxy resin and/or an epoxy resin (component C); the component B contains at least one compound that is selected from the group consisting of a surface treatment agent and a sizing agent; and a gas component that is obtained by heating the component B at 600°C for 12 seconds contains a carboxylic acid anhydride, or alternatively, a gas component that is obtained by heating the component B at 400°C for 12 seconds contains a compound that is represented by general formula (1). (In general formula (1), n represents an integer of 1 to 10; each X independently represents an alkylene group having 1 to 5 carbon atoms; and each Y independently represents an alkyl group having 1 to 5 carbon atoms.)
