STUDIES ON THE POLYMERIZATION OF FUNCTIONAL MONOMERS CONTAINING AMINO-GROUP XII Synthesis and Photopolymerization of a Novel Functional Monomers-Np-acryloyl-N'-Phenylpiperazines and Its Uses as a Component of Redox Initiation

我们曾报道了含芳香叔胺基功能性单体的合成及其聚合的研究,这些单体都是既参与引发反应又参与聚合的“引发剂单体”。本文报道了一种含有芳香叔胺基的新单体——N-丙烯酰-N′-苯基哌嗪(APP)和N-甲基丙烯酰-N′-苯基哌嗪(MPP)的合成及其光聚合。由于APP或MPP含有芳香叔胺基,它们和过氧化苯甲酰(BPO)配合,

N-acryloyl-N'-phenylpiperazine (APP) and N-methacryloyl-N'-phenylpiperazine (MPP) were synthesized by the reaction of N-phenylpiperazine with corresponding acryloyl chlorides. The solution of these polymers display the fluorescence phenomenon, but these monomers do not. APP and MPP can be photopolymerized under the UV irradiation. The rate equation of MMA polymerization initiated by APP and BPO is given as RP = [APP]0.5 [BPO]0.5 [MMA] . The redox initiation system would be formed by the. combination of APP and BPO. APP not only initiates the polymerization of MMA, but also incorporates into the MMA polymer chains.
