Title:
CROSSLINKED MOLDING AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/124223
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing a crosslinked molding in which permanent compression set is further reduced, and a method for manufacturing a crosslinked molding that us suitable for obtaining a crosslinked molding in which permanent compression set is further reduced, and whereby a single cycle of injection molding can be shortened when a crosslinked molding is obtained by compression molding. [Solution] The present invention pertains to a method for manufacturing a crosslinked molding, characterized by comprising melt-kneading a composition including a polymer having a terminal double bond, a hydrosilyl-group-containing compound (Y) having at least two hydrosilyl groups in each molecule thereof, a platinum-based catalyst (Z) for hydrosilicon crosslinking, and a reaction inhibitor (D), performing injection molding in a die, performing primary crosslinking in the die, and extracting the primary-crosslinked molding from the die, and then performing secondary crosslinking in a heating medium.
