ABSTRACT OF THE DISCLOSURE Filled vinyl compositions, useful as surface covering, comprising a well-defined mixture of at least two normally-solid thermoplastic vinyl chloride polymers, e.g., (i) vinyl chloride/vinyl acetate copolymer; vinylidene chloride/vinyl chloride copolymer; vinyl chloride/propylene copolymer; chlorinated polyethylene polymer; low molecular weight vinyl chloride/vinyl C2-C4 alkanoate/C2-C4alkene random terpolymer or a mixture thereof and (ii) vinyl chloride/vinyl acetate/ethylene terpolymer. The inclusion of a thermoplastic oxyalkanoyl polymer, e.g., epsilon- caprolactone homopolymer, with/without an antioxidant, e.g., a hindered phenol, yields compositions having good processing characteristics as well as products exhibiting improved mechanical properties such as impact strength. 1.
