三元乙丙橡胶丙烯酸正丁酯接枝物的表征和正交设计在共聚反应中的应用

THE CHARATERIZATION OF THE GRAFT COPOLYMER OF BA ONTO EPDM AND THE APPLICATION OF ORTHOGOND OPTIMUM DESIGN TECHINIQUE ON THE GRAFTCOPOLYMERIZATION

应用化学分析、红外光谱及接触角等方法对三元乙丙橡胶—丙烯酸丁酯接枝物进行了表征 ,用正交方法对溶液法三元乙丙橡胶上接枝丙烯酸正丁酯共聚反应进行了研究 ,找到了高接枝率的反应条件 。

The graft copolymer of butylene ACRYLATE (BA) onto random ethylenepropylenediene terpolymer (EPDM)was characterized by infrared spectra, chemical analysis and contact angle against water. The graft copolymerization of butylene acrylate onto random ethylenepropylenediene terpolymer with benzoyl peroxide as initiator and xylene as solvent was studied by orthogond optimum design technique, and the condition of graft copolymerization for highest grafting yield was obtained, moreover, the effects of the conditions on the grafting yield were preliminary discussed.
