UV-Light lnduced Crosslinking Reaction of Cinnamate Natural Rubbers:Effect of the Spacer Length,Counter-lon Nature,and Content

摘要

Maleated natural rubber was modified by introducing different contents of cinnamate groups,separated from the main chain by -(CH_2)n- spacers(n=2 to t).Residual carboxylic acid groups were neutralized as Li,Na,and K-salts.The kinetic behavior of these materials towards ultraviolet-induced crosslinking reaction was investigated and correlated with Tg.
