Abstract
A method for increasing the slip of polyolefins and improving the adhesion of water based inks of polyolefins by incorporating into the polyolefin an effective amount of a lactamide having the formula: ##STR1## wherein R is alkenyl having from about 12 to about 22 carbon atoms. Optionally, there can be included with the lactamide a finely divided inorganic material. Also disclosed are compositions of matter comprising a polyolefin, such as homopolymers and copolymers of ethylene and propylene, the aforedescribed lactamide and optionally a finely divided inorganic material. Also described is the new compound, N-erucyl lactamide.
Claims24
