系统研究了β-蒎烯与丙烯酸(AA)、丙烯酸甲酯(MA)、丙烯酸正丁酯(nBA)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸正丁酯(nBMA)、α-腈基丙烯酸乙酯(ECA)、丙烯腈(AN)、甲基丙烯腈(MAN)、富马腈(FN)、马来酸酐(MAh)、N-苯基马来酰亚胺(NPMI)和N-乙基马来酰亚胺(NEMI)等极性乙烯基单体(PVM)的共聚合行为。GPC、1H NMR和DSC等表征结果表明:β-蒎烯与以上各种PVM之间发生有效的自由基共聚合反应,添加合适的路易斯酸可以提高交替共聚合倾向和共聚物中β-蒎烯的嵌入率。采用可逆加成-断裂链转移(RAFT)聚合方法,在较低的β-蒎烯投料组成(Fβ-蒎烯=0.10)条件下还实现了β-蒎烯与AN、MA、nBA和NPMI等单体的“活性”/可控自由基共聚合。
The effects of β-pinene with acrylic acid (AA), methyl acrylate (MA), nBA, methyl methacrylate (MMA), n-butyl methacrylate Ethyl acrylate (ECA), acrylonitrile (AN), methacrylonitrile (MAN), fumaronitrile (FN), maleic anhydride (MAh), N-phenylmaleimide (NPMI) and N - Ethylene Maleimide (NEMI) and other polar vinyl monomers (PVM) copolymerization behavior. The results of GPC, 1H NMR and DSC showed that the free radical copolymerization between β-pinene and the above PVM was effective. The addition of suitable Lewis acid could increase the tendency of alternating copolymerization and β-pinene The embedding rate. By means of reversible addition-fragmentation chain transfer (RAFT) polymerization, β-pinene, AN, MA, nBA and NPMI were also achieved under the condition of low β-pinene feed composition Monomer “activity ” / controlled radical copolymerization.
