Abstract
A polymerisable ethylenically unsaturated macromonomer being the reaction product of: i) an adduct formed from the reaction of an unsaturated non-mineral oil reacted with an enophile having an acid, ester or anhydride moiety and ii) an ethylenically unsaturated monomer having a moiety reactive with the acid, ester or anhydride moiety of the enophile and iii) a chain extender material having at least two moieties reactive with the acid, ester or anhydride moiety of the enophile.
Claims20
A polymerisable ethylenically unsaturated macromonomer being the reaction product of
- i) an adduct formed from the reaction of an unsaturated non-mineral oil reacted with an enophile having an acid, ester or anhydride moiety and
- ii) an ethylenically unsaturated monomer having a moiety reactive with the acid, ester or anhydride moiety of the enophile and
- iii) a chain extender material having at least two moieties reactive with the acid, ester or anhydride moiety of the enophile.
A process of making a macromonomer comprising the steps of:
- i) reacting an unsaturated non-mineral oil with an enophile having an acid, ester or anhydride moiety, optionally in the presence of iodine, to form an adduct;
- ii) reacting the adduct with an ethylenically unsaturated monomer having a moiety reactive with the acid, ester or anhydride moiety of the enophile to form an intermediate;
- and
- iii) reacting the intermediate of step ii) with a chain extender material having at least two moieties reactive with the acid, ester or anhydride of the enophile.
