摘要

Abstract

The fluoresence behavior of N (2-methacryloyloxyethyl)-N-methy-p-toluidine (MEMT) monomer and its polymer has been investigated. It was observed that the monomer's fluoresence emission intensity was always lower than that of its polymer. This phenomenon was ascribed to the "structural self-queching effect". From the Stern-Volmer plots

the fluoresence quenching constant of PMEMT by different quenchers

i. e.

methacrylonitrile (MAN)

acrylo-nitrile (AN) fumadinitrile (FN)

tetracyanoethene (TONE)

methyl acrylate (MA)

methyl methacrylate (MMA) were evaluated respectively. The more the electron-poor of monomers (quenchers) the higher values of fluoresence quenching constants were obtained. MEMT itself would photo-induced AN polymerization. In the presenceof benzophenone (BP) and under UV light irradiation

photo-induced graft copolymerization of AN onto PMEMT and P(ME-MT-co-MA) would take place. The grafted polymers obtained were characterized by FT-IR spectra.
