ABSTRACT:
Oils derived essentially from petroleum and which are liquids at ambient room temperature and meet a certain molecular weight/percent paraffin content parameter may be used as the only necessary external lubricants for rigid vinyl halide resin compositions when said oils are added to the resin compositions in sufficient quantity to permit satisfactory molding and extrusion of the resulting resin compositions. Such oils may also be employed to form liquid lubricating and stabilizing compositions for rigid vinyl halide resin formulations which lubricating and stabilizing compositions are liquids at ambient room temperature or at temperature of about 50.degree. C. or less. Rigid resin compositions containing such oils and/or liquid lubricating and stabilizing compositions are readily prepared and easily processed.
