POLY(n-ALKYLACRYLATE) COMPOUNDS ABSTRACT OF DISCLOSURE A method of preparing an interpolymeric poly(n- alkylacrylate) of a molecular weight between about 3000 and 100,000 useful as a pour depressor in petroleum fractions comprising under polymerization conditions periodically introducing free radical polymerization catalyst via multiple time spaced additions in a heated initial mixture of n-alkyl- acrylate monomers, the polymerization being continued until a poly(n-alkylacrylate) is obtained having a molecular weight between about 3000 and 100,000, said initial mixture composed or n-alkylacrylate monomers wherein the alkyl distribution is or at least 18 carbons at least 70 wt. % of said alkyl is of C20 to C24 n-alkyl consisting of between about < and 65 wt. % of C20 n-alkyl, between about 18 and 65 wt. % C22 n-alkyl and between about 8 and 35 wt. % C24 n-alkyl; the product resulting from said method and a hydrocarbon fraction containing between about 4 and 15 wt. % macrocrystalline paraffin wax having incorporated therein a pour depressing amount of said poly(n- alkylacrylate) product wherein said poly(n-alkylacrylate) is initially introduced into the petroleum fraction at a tempera- ture above a substantial portion of said wax. -I-
