Abstract
Calixarene functional monomers incorporate an α-keto ester group on one side (rim) of the monomer, typically an upper rim, and a vinyl ester group disposed on an opposite side (rim) of the monomer to the α-keto ester group, typically a lower rim These functional groups at the two rims confer the capability of self-polymerisation when irradiated with UV light to form long homopolymer chains because of polymerizable vinyl ester groups, specifically; the α-keto ester group has been found to self-initiate polymerization without the need for a separate initiator, while the vinyl ester group allows UV-catalysed crosslinking of the monomers to provide a 3-D homopolymer matrix.
