Resin molded body and method for producing same

A resin molded article wherein a surface of a norbornene-based crosslinked polymer comprising at least one member selected from the group consisting of dicyclopentadiene-based monomer units, tetracyclododecene-based monomer units, and tricyclopentadiene-based monomer units in an amount of 50% by mass or more is coated with a polyamide-imide layer, and a method for producing the same. Since the resin molded article of the present invention has highly excellent heat resistance and durability, the resin molded article can be suitably used in applications that require heat resistance such as engine cover applications for automobiles and the like, and electric insulation applications.. ...

Gelling promoter

The present invention relates to a gelation promoting agent when polymerizing a norbornene-based monomer in the presence of a metathesis polymerization catalyst, the gelation promoting agent obtained by mixing an activator of the metathesis polymerization catalyst and a norbornene-based monomer, wherein the gelation promoting agent consists essentially of a mixture of only two components of the activator and the above norbornene-based monomer; and a liquid formulation for reaction injection molding containing the gelation promoting agent. The gelation promoting agent of the present invention is added to a liquid formulation for reaction injection molding, thereby exhibiting effects that the gelation when the liquid formulation contacts a catalyst can be shortened. ...

Method for producing composite molded article

. . The present invention relates to a method for producing a composite molded article having a flexural modulus at 150° c. Of 25% or more of a flexural modulus at 23° c., including the steps of (1) placing glass fibers in a mold; (2) impregnating glass fibers with a polymerizable composition containing a cycloolefin monomer, a metathesis polymerization catalyst, a radical generator, and a compound represented by the general formula (i); (3) subjecting the above polymerizable composition with which the glass fibers are impregnated to a bulk polymerization to provide a composite molded article; and (4) demolding the composite molded article; and a composite molded article obtained by the above method. ...
