PURPOSE:To form a heat-shrinkable vinyl chloride series resin-molded article whose surface is mat, by applying molding and orientation processing to a resin composite having vinyl chloride series resin, which has been crosslinked partially, for its main ingredient. CONSTITUTION:A film and tube whose surfaces are mat can be obtained easily by performing molding by making use of vinyl chloride series resin, which has been crosslinked partially, as molding raw materials and an excellent heat- shrinkable molded article can be obtained by applying heating and orientation processing to the film and tube. The partially crosslinked vinyl chloride series resin can be manufactured by a method wherein a quantity of a multifunctional monomer corresponding to a desired degree of crosslinking is made to exist in polymer series at the time of polymerization of a vinyl chloride monomer or a mixture of vinyl chloride and the other vinyl chloride monomer through a device such as a suspension polymerization method. As for a molding method, a device manufacturing a heat-shrinkable molded article made of vinyl chloride resin is usable generally.
