Abstract
A vinyl chloride resin composition providing a rubbery elastic material small in temperature dependence of hardness which is composed mainly of 100 parts by weight of a vinyl chloride resin comprising 8-90% by weight of a tetrahydrofuran-insoluble gel fraction and the remainder of a tetrahydrofuran-soluble fraction, 10-200 parts by weight of a copolyester resin and 25-200 parts by weight of a plasticizer, and tubes and curl cords obtained using the composition.
