Abstract

PURPOSE: When a molded product with a specific crosslinking index is made from a vinyl chloride resin composition, precrosslinking is effected until the crosslinking index reaches higher than half level, then the molding and crosslinking are completed simultaneously, thus preventing the scorch during the molding.
CONSTITUTION: When a molded product with a crosslinking index ranging 0.005W 5, preferably from 0.05W1, which is defined as the number of crosslinking points per one molecule before crosslinking, when crosslinking occurrs between linear high-molecular molecules, is made from a vinyl chloride resin composition that contains a vinyl chloride homo- or copolymer and has crosslinking properties, a blender or mixing roller is used to effect the precrosslinking of the composition to a level of higher than 50, preferably higher than 80% of the crosslinking index of the molded product. Then, the resultant crosslinked resin is molded with an extruder and simultaneously crosslinking is completed.
EFFECT: Scorcing (caused by partially early crosslinking) is prevent to give molded products with improved appearance.
