Thermoplastic resin composition and a method for the production thereof
Abstract
Abstract THE THERMOPLASTIC RESIN COMPOSITION OF THE PRESENT INVENTION IS A MIXTURE OF 99 TO 10 PARTS BY WEIGHT OF A POLYVINYL CHLORIDE RESIN AND 1 TO 90 PARTS BY WEIGHT OF AN AROMATIC POLYSULFONIC RESIN HAVING SUPERIOR HEAT RESISTANCE TOGETHER WITH AN IMPROVED IMPACT STRENGHT, AND IS SUITABLE FOR USE AS ARTICLES FOR CHEMICAL INDUSTRIES, CONSTRUCTION MATERIALS, ETC. THIS THERMOPLASTIC RSIN COMPOSITION IS MOST ADVANTAGEOUSLY PRODUCED BY MIXING POLYVINYL CHLORIDE AND AROMATIC POLYSULFONE CONTAINING A STABILIZING AGENT FOR POLYVINYL CHLORIDE, SUCH AS DIBUTYL TIN DILAURATE, DIBUTYL TIN MALEATE, TIN MERCAPTIE, LEAD OXIDE, TRIBASIC LEAD SULFATE, DIBASIC LEAD PHOSPHITE, DIBASIC LEAD STEARATE, CADMIUM STEARATE, BARIUM STEARATE, ALKALINE EATH SILICATES, HYDROQUINONE OR EPOXIDE AND A STABILIZING AGENT FOR AROMATIC POLYSULFONE, SUCH AS NAPHTALENE THIOL, BENZIMIDAZOLE, ORGANIC SULFIDES, IMIDES, PHOSPHATES OR ORGANO TIN COMPOUNDS, ADDING A LOW MOLECULAR WEIGHT COMPOUND SUCH AS AN AROMATIC HYDROCARBON, A CHLORINATED HYDROCARBON, A KETONE, AN ESTER OR AN ETHER TO THE MIXTURE AND THEREAFTER REMOVING THE LOW MOLECULAR WEIGHT COMPOUND.
