摘要： PROBLEM TO BE SOLVED: To provide a diallyl phthalate-based resin impregnated paper cloth for short time molding exhibiting effects capable of obtaining a facial board having excellent surface properties even in a low pressure and short time molding and attaining a high productivity because of molding under a low pressure in a short time by selecting a hardener suitable for molding of a diallyl phthalate-based resin under a low pressure in a short time, that is, an organic peroxide having 157-166 deg.C one min half-life temperature. SOLUTION: This impregnated paper cloth is obtained by impregnating or coating a diallyl phthalate-based resin composition comprising 100 pts.wt. of a blended resin of 30-90 wt.% of diallyl phthalate prepolymer with 10-70 wt.% of an unsaturated polyester and 2-6 pts.wt. of a peroxyester or a peroxyketal as an organic peroxide having 157-166 deg.C one min half-life temperature as a hardener on a base material to be impregnated.

摘要： PROBLEM TO BE SOLVED: To provide a decorative plate from which stains can easily be wiped with a dry cloth or paper when being stained with an oil-based marker or the like, and which has a highly surface glossiness and shows excellent in water resistance, weather resistance and chemical resistance and the like. SOLUTION: A stain resistant glossy decorative plate is obtained by laminating a paper cloth produced by impregnating a base material with a resin composition comprising a diallylphthalate-based thermosetting resin composition for a decorative plate of 100 pts.wt., a polyether-modified silicone having an acryloxy group or a methacryloxy group of 3 to 50 pts.wt. and a hardening agent for the thermosetting resin on the decorative plate base material and by heating and pressing the composite.

摘要： PROBLEM TO BE SOLVED: To provide a process for preparing a post-curable diallyl phthalate prepolymer having excellent properties such as electrical properties, heat resistance, chemical resistance and dimensional stability as a thermosetting resin. SOLUTION: There is provided a process for producing a diallyl phthalate prepolymer from a diallyl phthalate monomer by solution polymerization, which process comprises using hydrogen peroxide as the polymerization initiator, using 200-500 pts.wt., per 100 pts.wt. diallyl phthalate monomer and a, solvent selected among 2-propanol, 2-butanol and 2-methyl-1-propanol, performing the polymerization at 120-180 deg.C under elevated pressure, stopping the reaction when a part of the reaction solution is withdrawn from the reactor and then becomes turbid when cooled to 80-140 deg.C and separating the prepolymer precipitated after cooling. This process can provide a diallyl phthalate prepolymer from a diallyl phthalate monomer in high yields, and unlike a conventional process, can dispense with the extraction of the prepolymer with a large amount of a solvent because the prepolymer can be precipitated by simply cooling the reaction solution.
