Abstract

Multifunctional crosslinkers having two, three, four and six functionalities were synthesized using a convergent method and were applied to a photocrosslinking system having thermally degradable properties. The multifunctional crosslinkers contained epoxy units and tertiary ester linkages. When the blended films of epoxides/poly(p-vinylphenol) with a photoacid generator were irradiated and followed by baking at relatively lower temperatures ( 120 °C). The reaction pathway of the blended system was studied by in situ FT-IR measurements.
