Studies on Photosensitive Polymers (). Syntheses of Naphthoquinone-1,2-diazide-5-sulfonyl Esters with Backbone Resins
[摘要] Polymers with photosensitive functional groups, the naphthoquinone-1,2-diazide-5-sulfonyl esters(PGND, BEND and PVAND) of polyglyceryl phthalate(PG), bisphenol A-epichlorohydrin polycondensate(BE) and polyvinyl alcohol(PVA), were prepared. The molecular weights of the starting materials were determined by the cryoscopic method, i.e., in the range of 650~1200 for PG and 780~1320 for BE, PGND, BEND and PVAND were prepared by esterification of PG, BE and PVA with naphthoquinone-1,2-diazidie-5-sulfonyl chloride, and the replacements of such a functional groups were confirmed by the infrared absorption spectra and elemental analyses. The good agreement between the observed values of elemental analyses (PGND, BEND and PVAND) and the calculated values, indicated that the degree of polymerization did not change in the course of esterification of PG, BE and PVA.
