甲基丙烯酸

IR, SEM and TEM showed that the encapsulation film, which is composed of poly modified by silane, is a dense reticulation with a thickness of 20~30nm.

IR、SEM和TEM测试结果表明，该有机包覆层由硅烷改性的聚甲基丙烯酸甲酯组成，是一种厚度为20~30nm的致密网状膜。

The results show that water salability and water dispersion stability are excellent when the mass fraction of GMA is 15%, the ambition ring-open is 50% and neutralization is 80%.

结果表明：甲基丙烯酸缩水甘油酯含量为15%，胺化开环址为50%，中和度为80%时，树脂的水溶性及水分散体系稳定性均良好。

Two types of latex particles with similar particle size, similar molecular weight and molecular weight distribution of their constituent polymers labeled by the donor phenanthrene or by the acceptor a polymerizable benzophenone were synthesized by seeded semicontinuous emulsion polymerization.

利用这些乳液粒子，研究了聚甲基丙烯酸丁酯在不同的温度下在其薄膜中的扩散，获得了不同温度时的表观扩散系数以及聚合物扩散的表观活化能。

When SiO〓-NH〓-Rh-Co complex was used to catalyze the hydroformylation of methyl methacrylate, an optimal conversion of 93.4% and optimal selectivity of 84.4% for the normal aldehyde were both obtained at Rh/Co ratio of 2/1, which were both higher than that catalyzed by SiO〓-SiNH〓-Rh and SiO〓-Si-NH〓-Co momometallic catalysts. Clearly a synergistic action between Rh and Co atoms presented in the complex.

我们以SiO〓-Si-NH〓-Rh-Co催化甲基丙烯酸甲酯的醛化反应，当催化剂中Rh/Co比为2/1时，催化活性最高，可达93.4％，对正构产物β-甲酰异丁酸酯的选择性达到84.4％，都高于单金属催化剂，表明了金属间存在相互作用。

The surface of sisal fiber was modified by alkali treatment and graft-polymerization of methylmethacrylate, respectively.

分别用碱处理和甲基丙烯酸甲酯接枝聚合的方法对SF进行表面改性。

I have MMA gloves from Canbox.ca, and they make my fists feel like a couple of rocks…and definately not good for your sparring partner's face!

我有甲基丙烯酸甲酯手套从canbox.ca ，他们让我的拳头觉得像一对夫妇的岩石……而且，绝对不是良好的为您掀起合作伙伴的脸！

Therefore, the linearized equation representing the dependence of Tg on the content of iso-, syndic- and heterotriads can only be used for the PMMA with the same type of stereodiads distribution.

本文研究了聚甲基丙烯酸甲酯的立构规整性与T8的关系，结果表明立构单元分布和含量均对T8有显著影响。

In the meantime, I want to discuss what qualities a trainee who's new to MMA should strive for.

在此同时，我想讨论什么样的品质学员谁的新的甲基丙烯酸甲酯应该争取。

Objective To evaluate the clinical effect of treating thoracolumbar tumorous pain by percutaneous vertebroplasty.

目的 评价经皮穿刺骨水泥聚甲基丙烯酸甲酯灌注椎体成形术治疗胸腰椎肿瘤疼痛的疗效。

Dana White, of the UFC, credited Bruce Lee as the first to practice MMA in America.

达纳白色的UFC，记为第一个在美国的甲基丙烯酸甲酯的做法李小龙。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
