摘要： In producing chlorinated polyvinyl chloride resin having chlorination degree of 60-73% by weight, wherein polyvinyl chloride resin is suspended in an aqueous medium and chlorine gas is blown into said suspension under beam of a mercury lamp in the temperature range of 40-90° C., an organic peroxide compound having a 10 hour half-life in the range of 40-90° C. is added into the reaction vessel in the ratio of 0.01-1 parts to 100 parts of the polyvinyl chloride resin by weight before the chlorination reaction is started. By this method, the time for chlorination reaction can be shortened without sacrificing the initial coloring and the heat stability, whereby chlorinated polyvinyl chloride can be produced with significantly improved productivity.

摘要： A continuous process for producing reinforced resin laminates is disclosed. A plurality of fibrous substrate is continuously and sequentially subjected to the steps of (a) impregnating with resin, (b) laminating into a unitary member, (c) sandwiching between a pair of covering sheet, at least one of which is a cladding metal foil, and (d) curing the resin while supporting between said covering sheets without applying pressure on the laminate surface.

摘要： A continuous process for producing reinforced resin laminates comprising the steps of impregnating a fibrous substrate with a liquid resin which is free of volatile solvent and is capable of curing without generating liquid and gaseous byproducts, laminating a plurality of the resin-impregnated substrates into a unitary member, sandwiching the laminate between a pair of covering sheets, and curing the laminate between said pair of covering sheets without applying appreciable pressure. The improvement comprises adjusting the final resin content in said resin impregnated substrate at 10 to 90% by weight based on the total weight of said impregnated substrate.
