The tensile strength of CPE vulcanizates modified by in situ formed NaAA and LiAA is more than 30MPa and 28MPa, respectively.

原位合成丙烯酸盐改性CPE硫化胶在电解质水溶液中的吸水膨胀率比在去离子水中低得多，浓度越高这种效应就越强烈；温度提高可使硫化胶的吸水膨胀速度提高，在常温到60℃之间，吸水膨胀率随着温度的提高而增大，但超过60℃平衡吸水膨胀率则随着温度的提高而降低；硫化胶的吸水膨胀过程并不是单一的菲克扩散，其中还包括聚丙烯酸盐和橡胶分子链的松弛。

When the resinic demulsifiers is are synthesized using solvent polymerization, it is found that the dosages of butyl acrylate, methacrylic acid and initiating agent in demulsifiers all exist optimum values; with the demulsifiers concentrations' increasing, the dehydration rate increases, however, it increases with the salinity's increasing.
