Vinyl chloride polymer compositions, solid films obtained therefrom, and a floor covering having such a film as a wear layer.

摘要

In the production of solid films (e.g. a floor covering wear layer) by casting, fusing and then cooling a vinyl chloride polymar plastisol, good physical properties of the plastisol and films are provided by use of a prime plasticizing ester containing at least 40% by weight of diester selected from alkyl benzyl succinates, glutarates and mixtures thereof. The amount of prime plasticizing ester used is less than the 35 phr generally regarded as the minimum for satisfactory plastisol formation and/or film plasticization, and by using such small amounts of ester, the films have unusually high stain resistance.
