摘要： PURPOSE:To contrive an improvement in mold release properties from a shaped material, by a method wherein a norbornane lumpy polymeric layer possessing an uneven pattern of a shaping form is allowed to contain paraffin and wax which are comprised substantially of carbon and hydrogen and solid at a room temperature. CONSTITUTION:A resin layer comprised of a norbornane lumpy polymer is molded by a reaction injection molding method and made into a shaping form wherein an uneven pattern is formed easily on the surface. Either 0.5-50 pts. paraffin or wax comprised of a hydrocarbon compound is contained in the lumpy polymer on the basis of the 100 pts. polymer. At the time of peeling of concrete after placement of the concrete to the shaping form, its peeling properties are improved, the concrete does not adhere to the shaping form even to an uneven decorative face and the form can be used repeatedly.

摘要： PURPOSE:To manufacture a metathesis polymer molded article having no unfilled parts or air voids without obstructing metathesis polymerization or bringing about the lowering of the physical properties of a resin or the appearance deficiencies of the molded article and using gas dangerous from the aspect of work by substituting the air in a cavity with vapor of a norbornene compd. to suppress the generation of air bubbles becoming a problem in the case of 'vacuum molding'. CONSTITUTION:A liquid raw material monomer containing a metathesis polymerization catalyst is injected into the cavity of a mold to be polymerized to produce a cured polymer molded article. In this method, the air in the cavity is preliminarily sucked before the liquid raw material in the cavity of the mold is injected to reduce the pressure in the cavity and, after the air in the cavity is substituted with the vapor of a norbornene compd., the liquid raw material is injected in the cavity of the mold to produce the metathesis polymer molded article. The pressure in the cavity after the air in the cavity is substituted with the vapor of the norbornene compd. is set to 7kPa or more.

摘要： PURPOSE:To provide a filter plate with good size precision and high durability and heat resistance by injecting a liquid resin composition containing a metathesis catalyst and norbornene-based monomer at a specified ratio into dies for forming filtration plates to give norbornene-based monomer bulk polymer and at the same time to from the polymer. CONSTITUTION:A liquid resin composition containing a metathesis catalyst and 50wt.% or more of norbornene-based monomer is injected into filter plate forming dies consisting of a male type die and a female die to make norbornene- based monomer bulk polymer and at the same time to form the polymer and thus a filter plate is obtained. Since the dies' necessary temperature at the time of polymerizing and forming is low (about 250 deg.C or lower), the temperature difference of the resin surface and the center part at the time of forming is small and consequently cracks are hardly formed inside a formed article. As a result, size precision of the formed article is good. The norbornene-based monomer bulk polymer has high strenght, waterproofness, resistance to chemicals as well as heat resistance and the polymer can be adhesion-mended with an adhesive.
