Abstract
A method of making a polymerisable ethylenically unsaturated macromonomer comprising the steps of: i) providing a chosen unsaturated non-mineral oil or a mixture of unsaturated non-mineral oils having a first blend of triglycerides, ii) treating the mixture of oils with a transesterification catalyst to produce a second blend of triglycerides different to the first, iii) reacting the second blend of triglycerides with an enophile having an acid, ester or anhydride moiety to form an adduct, iv) 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, v) reacting the intermediate of step (iv) with a chain extender having at least two moieties reactive with the acid, ester or anhydride moiety of the enophile to form the ethylenically unsaturated macromonomer.
