Alkylacrylate alkanediol methacrylate interpolymers and pour depressed compositions thereof

Abstract

Abstract AN INTERPOLYMER OF AN AN-ALKYLACRYLATE MIXTURE AND AN N-ALKANEDIOL DIMETHACRYLATE OF FROM 10 TO 18 CARBONS, SAID INTERPOLYMER HAVING A WEIGHT RATIO OF SAID N-ALKYLACRYLATE MIXTURE TO SAID ALKANEDIOL DIMETHACRYLATE OF BETWEEN ABOUT 99.5:0.5 TO 95:5 AND A MOLECULAR WEIGHT BETWEEN ABOUT 3000 AND 100,000 AND A MOLECULAR WEIGHT IN SAID N-ALKYL MIX IS OF AT LEAST 18 CARBONS AND AT LEAST 70 WT. PERCENT OF SAID ALKYL IS BETWEEN 20 AND 24 CARBONS INCLUSIVELY, THE C20 TO C24 ALKYL GROUP CONSISTING OF BETWEEN ABOUT 2 AND 65 WT. PERCRNT OF C20 ALKYL, BETWEEN ABOUT 18 AND 65 WT. PERCENT C22 ALKYL AND BETWEEN ABOUT 8 AND 35 WT. PERCENT C24 ALKYL; AND A WAXY HEAVY PETROLEUM FRACTION CONTAINING BETWEEN 4 AND 15 WT. PERCENT MACROCRYSTALLINE PARAFFIN WAX HAVING INCORPORATED THEREIN A POUR DEPRESSIG AMOUNT OF SAID INTERPOLYMER WHEREIN SAID INTERPOLYMER IS INITIALLY INTRODUCED IN THE WAXY HEAVY PETROLEUM FRACTION AT A TEMPERATURE ABOVE THE SOLUTION POINT OF THE MACROCRYSTALLINE WAX COMPONENT THEREIN.
