Abstract
A process of making a polymerisable ethylenically unsaturated macromonomer from an unsaturated non-mineral oil, the oil being a mixture of triglycerides, some of which comprise at least one fatty acid having at least two non-conjugated unsaturated bonds at least one of which is ethylenically unsaturated, the process comprising the steps of: i) conjugating the non-conjugated unsaturated bonds, ii) reacting the reaction product of step (i) with an enophile having an acid, ester or anhydride moiety to form an adduct, iii) reacting the adduct with an ethylencially unsaturated monomer having a moiety reactive with the acid, ester or anhydride moiety of the enophile to form an intermediate iv) reacting the intermediate of step (iii) with a chain extender having at least two moieties reactive with the acid, ester or anhydride moiety of the enophile to form the macromonomer, where the oil has an iodine value of from 110 to 180 g of iodine per 100 g of oil.
