SYNTHESES AND REACTIONS OF PHOTOPOLYMERS .2. INTERFACIAL POLYCONDENSATION, MICROENCAPSULATION, PHOTODEGRADATION, RELEASE MEASUREMENTS

Photosensitive microcapsules, which are thermally quite stable, are fo rmed via interfacial polycondensation in which one of the shell-formin g reactants contains an azo function. An azo monomer, containing alpha ,omega-carboxylic diacid dichloride was reacted with a trifunctional a liphatic amine on the oil-water interface resulting in a shell-forming crosslinked polyamide. The size of the resulting photosensitive micro capsules was determined. It could be shown that these microcapsules ca n be opened by means of UV-light.
