Abstract
A composition comprises 100 parts by weight of a vinyl chloride type resin and 25 to 200 parts by weight of a plasticizer, the vinyl chloride type resin being composed of 1 to 90% by weight of tetrahydrofuran-insoluble gel fraction and the balance of tetrahydrofuran-soluble fraction. This composition gives a rubbery elastomer having an excellent heat deformation resistance and an excellent matt finish and a small compression permanent set. Though it is close to rubber in properties, the composition has a moldability and processability similar to those of conventional thermoplastic resins, and can be formed into a sheet for interior material of automobile, a packing, a tube, etc.
