The EPDM vulcanizates modified by in situ formed NaAA also have good mechanical and water-swelling properties.

从实验结果可以看出：在以上原位合成丙烯酸盐改性橡胶的配合体系中，随着NaAA或LiAA含量的增大，硫化速度、硫化程度、吸水膨胀性能和力学性能均有提高。

The in situ formed NaAA could improve the mechanical properties and the water-swelling properties of the EPDM/NaAA vulcanizates.

吸水膨胀橡胶是在橡胶基体材料中引入亲水性官能团或亲水性组分制成的，其制备方法可分为化学法和物理共混法。

The results showed that the in situ formed LiAA and NaAA have preferable modified effect on CPE than the KAA, MgAA and ZnAA.

实验结果表明：与原位合成KAA、MgAA和ZnAA相比，原位合成LiAA和NaAA对CPE橡胶具有较好的改性作用。

The CPE vulcanizates modified by in situ formed NaAA and LiAA have high tensile strength.

基于上述对比实验的的结果，着重针对三元乙丙橡胶、丁腈橡胶和氯化聚乙烯等三种典型的橡胶，考察了有机过氧化物用量、原位合成NaAA或LiAA含量及酸碱摩尔配比对硫化胶性能的影响。

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。

Through the neutralization of sodium hydroxide and acrylic acid, NaAA was in-situ prepared in ethylene-vinyl acetate copolymer during mixing and used to reinforce EVM cured by dicumyl peroxide.

研究了NaAA用量对EVM硫化胶吸水前后力学性能的影响，并考察了NaAA用量及浸泡介质对EVM硫化胶吸水膨胀性能的影响。

The dissertation focused on CPE, NBR and EPDM modified by in situ formed LiAA and NaAA.

DCP用量增大，导致吸水膨胀率下降，但仍然可提高硫化特性和力学性能。

The effects of DCP content, content of in situ formed LiAA or NaAA and LiOH/AA or NaOH/AA molar ratio on the mechanical and water-swelling properties of the vulcanizates were discussed.

同时，硫化胶的力学性能和吸水膨胀性能在很大程度上取决于酸碱摩尔比，过量的AA会给硫化胶的性能带来不利的影响，但碱稍微过量（MeOH/AA摩尔配比为1.0～1.1）对硫化胶的性能影响并不大。

The water-swelling ratio of the modified CPE vulcanizates by in situ formed acrylate have the gradation as LiAA＞NaAA＞KAA＞MgAA＞ZnAA＞CPE gum.

含有各种原位合成丙烯酸盐CPE硫化胶的吸水膨胀率按如下顺序变化：LiAA＞NaAA＞KAA＞MgAA＞ZnAA＞纯CPE硫化胶。

The CPE/LiAA and CPE/NaAA compounds have good curing properties. The tensile strength is about 30MPa when the in situ formed LiAA or NaAA content is 30phr.

其混炼胶的硫化速度快、硫化程度高；当其含量为30份时，硫化胶拉伸强度可达30MPa左右；硫化胶吸水膨胀速度快，浸水24小时后原位合成LiAA和NaAA改性CPE硫化胶的吸水膨胀率分别可超过120％和85％。
