摘要
以大分子(bBr-iBE)为引发剂,以溴化铜(CuBr_2)为催化剂,以五甲基二乙烯三胺(PMDETA)为配体,通过电子转移再生活化剂-原子转移自由基聚合(ARGET-ATRP)合成了一种新型的相对分子质量可控且分布较窄的含羟基聚丙烯酸酯类嵌段聚合物分散剂,并与市场上常用的分散剂进行了应用性能比较。
According to the electron transfer and activator atom transfer radical polymerization （ ARGET-ATRP ） principle, a new type of hydroxyl containing polyacrylate block polymer dispersant with controllable molecular weight and narrow molecular weight distribution was synthesized by macromolecule （ bBr-iBE ） as initiator, copper bromide （ CuBr2 ） as catalyst and pentamethyldiethylene triamine （ PMDETA ）as reaction ligand. And the application performances comparison between the new dispersant and commonly used dispersants in the market was conducted.
