Polyvinyl chlorides are plasticized by chlorinated gas oil which has been modified either (a) by fractionation between the limits 185-225 DEG C. or 225-255 DEG C. or 255-285 DEG C. or 285-320 DEG C., or (b) by admixture with tricresyl and/or other triaryl phosphate showing no tendency to exudation. There is no exudation of plasticizer from the product. |
