The properties of modified product of acrylic phenolic resin containing quaternary ammonium salt groups (APRQA)

and the effect of chemical modification on solubility

thermal property

and photo-crosslinking property

were studied in this paper. The experiment results showed that the modified resin exhibits much lower decomposition temperature and has good solubility in water

ethanol

DMSO

and DMF. After 30?min

thermocured at 160℃

the product of modified resin becomes insoluble in water. The photo-crosslinked film of modified resin has good physical properties as that of APRQA
