Abstract

A pour point depressant polymer composition comprises a polymerised ester. The polymerized ester consists of (a) methacrylic acid; and (b) an alcohol blend. The alcohol blend comprises alcohols selected from a group of alcohols consisting of (i) at least one alcohol selected from C10 linear alcohol in the range of 0 - 15 %; (ii) at least one alcohol selected from C12-C14 linear alcohols with 1% hydrocarbon in the range of 40 - 70 % of the total mass of the blend; (iii) at least one alcohol selected from C12-C14 linear alcohols with 6% hydrocarbon is in the range of 30 - 60% of the total mass of the blend; and (iv) at least one alcohol selected from C16-C18 linear alcohols in the range of 3 - 20% of the total mass of the blend and a process for the preparation of the same.
