  • Stain-resistant vinyl chloride polymer compositions plasticized with alkylbenzyl succinates, glutarates or mixtures thereof
    Patent number: 4243571
    Abstract: In production of solid films (e.g. a floor covering wear layer) by casting, fusing and then cooling a vinyl chloride polymer plastisol, good physical properties of the plastisol and films are provided by use of surprisingly small amounts of plasticizing ester including diester selected from alkyl benzyl succinates, glutarates and mixtures thereof. Using such small amounts of ester, the films have unusually high stain resistance.
