Abstract: Catalyst residue is removed from amorphous polypropylene product by water washing the polypropylene to remove water-soluble impurities therefrom, removing the resultant water, and thereafter dissolving the polypropylene in a hydrocarbon solvent having a boiling point below about 300*F. The catalyst residue is then filtered from the hydrocarbon solution of polypropylene.
Abstract translation: 通过水洗聚丙烯以除去水溶性杂质，去除所得水，然后将聚丙烯溶解在沸点低于约300°F的烃溶剂中，从无定形聚丙烯产物中除去催化剂残余物。然后将催化剂残余物 从聚丙烯的烃溶液中过滤。

Abstract: THE DARKENING AND DISCOLORATION OF LUBRICATING GREASES AND OILS INDUCED BY THE USE OF METAL SALTS OF SUBSTITUTED DITHIOCARBAMIC ACID ARE EFFECTIVELY PREVENTED BY THE INCLUSION OF SMALL AMOUNTS OF POLY(PHENYLENE SULFIDE) IN THE LUBRICATING COMPOSITON.
