Abstract
The present invention is a method for producing a resin-formed article, the method comprising melt-forming a forming material including a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 260° C. or higher and a syndiotacticity higher than 90%. Thus provided is a method for producing a resin-formed article sufficiently reflecting the properties of the hydrogenated crystalline dicyclopentadiene ring-opening polymer.
Claims5
A method for producing a resin-formed article, the method comprising
- adding a hydrogenation catalyst and then hydrogen to a system including a dicyclopentadiene ring-opening polymer to thereby hydrogenate the carbon-carbon double bond present in the dicyclopentadiene ring-opening polymer,
- obtaining a forming material including a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 265° C. or higher and a syndiotacticity higher than 90% from the system, and
- melt-forming the forming material,
- wherein the hydrogenation catalyst is selected from a group consisting of RuHCl(CO)(PPh3)3, RuHCl(CO)[P(p-Me-Ph)3]3, RuHCl(CO)(PCy3)2, RuHCl(CO)[P(n-Bu)3]3, RuHCl(CO)[P(i-Pr)3]2, RuH2(CO)(PPh3)3, RuH2(CO)[P(p-Me-Ph)3]3, RuH2(CO)(PCy3)3, RuH2(CO)[P(n-Bu)3]3RuH(OCOCH3)(CO)(PPh3)2, RuH(OCOPh)(CO)(PPh3)2, RuH(OCOPh-CH)(CO)(PPh3)2, RuH(OCOPh-OCH3)(CO)(PPh3)2, RuH(OCOPh)(CO)(PCy3)2, Raney nickel, nickel diatomaceous earth, nickel acetate, palladium acetate, PdCl2, and RhCl(PPh)3.
