Abstract
A process for preparing functionalised microporous polymers (which are also known as micro-cellular polymers or polyHIPE polymers (PHPs)) using intensified internal heating (for example by microwave irradiation).
Claims38
A process for preparing a functionalised polyHIPE polymer comprising:
- (a) obtaining in a first phase a polymerisable component, said polymerisable component comprising a functionalisable moiety;
- (b) obtaining a second phase;
- (c) forming a high internal phase emulsion of the first phase and the second phase, wherein the first phase and the second phase are at least partially immiscible;
- (d) causing polymerisation of the polymerisable component into a polyHIPE polymer, wherein a functionalising agent is present in the first phase or second phase or the first phase and the second phase or is added to the polyHIPE polymer;
- and
- (e) subjecting the polyHIPE polymer to intensified internal heating to cause functionalisation of at least a proportion of the functionalisable moieties.
