Abstract

A method of removing contaminating synthetic polymers from fats or greases, esp. for removing polyethylene from tallow, consists of raising the fat to a temp. between its melting pt. and 95 degrees C, thus making the polymers insol. in it, and then removing the polymers, pref. by filtration.
