Abstract
PURPOSE: To contemplate the utilization of vinyl chloride resins as a resin having high flex temperature, by a method wherein at least one member selected from activated clay, acid clay and activated carbon and at least one cpd. selected from MgO and Mg(OH)2 are added to a nonrigid vinyl chloride resin contg. a plasticizer and the mixt. is heat-treated.
CONSTITUTION: In order to reuse vinyl chloride resin products (agricultural film, sheet, leather, etc.) contg. a plasticizer and having low flex temperature, 5W100pts.wt. of at least one member selected from activated clay, acid clay and activated carbon and 1W30pts.wt. of at least one cpd. selected from MgO and Mg(OH)2 are added to 100pts.wt. of the vinyl chloride resin. The mixt. is blended under heating to produce a resin compsn. having a high flex temperature (corresponding to that of rigid vinyl chloride resins). The plasticizer contained in the nonrigid vinyl chloride resin is adsorbed by the clays and the activated carbon, or part of the plasticizer is decomposed by them to lose the plasticizing action. The Mg cpd. absorbs HCl which is evolved during heat treatment. In this way, the process enables the nonrigid vinyl chloride resin to be used for the same purpose for that rigid vinyl chloride resins are used.
