| Title of Invention | A PROCESS FOR THE SYNTHESIS OF A NOVEL OIL SOLUBLE CO POLYMER OF ATACTIC POLYPROPYLENE GRAFTED WITH LONG CHAIN ALKYL A DRYLATES FOR USE AS POUR POINT DEPRESSANT ADDITIVE IN LUBRICATING MINERAL OILS. |
|---|---|
| Abstract | ABATRACT:- ATACTIC POLYPROPYLENE OBTAINED AS A WESTE FROM COMMARCIAL POLYPROPYLENE PRODUCTION PLANT WAS GRAFT COPOLYMSRIZED WITH LONG 4HA IN AIKYL ACRYLATES USING BENZUYLPEROXIDE AS RADICAL INITIATOR IN TOLUENE SOLUTION,. RTLKYL CHAINS WERE EITHER LINEAR OR BRANCHED WHILE THEIR CHAIN LENGTH VARIED FROM M0 TO L 22, THE POLYPROPYLENE CONTENT IN THE GRSFT COPOLYMER VERIED FROM 50-95 WEIGHT PERCENT*. THESE GRAFT COPOLYMERS SHOWED A POUR POINT DEPRESSION TO THE EXTANT OF 9 TO 21 C FOR VIRGIN BA3E OILS OF 150 AND 500 SUS VISCOSITY AT A TREATMENT LEVEL OF 0.1 TO 0.5 WEIGHT PERTENT. |
