Nanomorphology control in aqueous coatings

Using catalytic chain transfer polymerisation (CCTP) in emulsion polymerisation results in efficient molecular weight reduction. An additional benefit of polymers prepared with CCTP is that they have a chain terminal unsaturated group that can be used in a subsequent graft copolymerisation to yield comb-shaped polymer chains. By careful optimisation of the polymer parameters, film properties can be optimised to yield coatings with very interesting combinations of properties.
