摘要
马来酸酐在乙丙橡胶上的接枝共聚,用过氧化苯甲酰为引发剂的效果优于偶氮二异丁腈。研究了温度、马来酸酐用量和引发剂用量等对接枝率的影响。用红外光谱和薄层色谱证明了接枝物的存在。用接触角技术测定了接枝物的表面性能。
Maleic anhydride was grafted onto ethylene-propyleue rubber.The re-sults showed that benzoyl perpoxide was superior to 2,2-azo-bis-isobuty-ronitrile as an initiator,and the effects of various reaction parameters inclu-ding reaction temperature,concentration of maleic anhydride aud benzoylperoxide,on the percentage of grafting were studied.The existene ofgrafted copolymer was verified by IR spectra and thin layer chromatography.The surface property of grafted copolymer was measured by contact angleagainst water.
