甲基丙烯酸

More and more polymeric surface active agents were used in pigment modification. In this paper, methyl cellulose, sodium polyacrylate and polyglycol were chosen to study the influence of molecular weight and stucture on properties of pigments.

论文中选用的高分子表面活性剂有天然高分子甲基纤维素和聚乙二醇、聚丙烯酸钠等合成高分子，考察了活性剂分子量、结构及用量对颜料性能的影响。

Microcapsules adventatial can be used by hydrophilic polymers for material, such as glutin, pectoylic, agaragar, aclylate cellulytic and methacrolein.

微囊外膜可由亲水性的高聚物作材料，如明胶、果胶、琼脂、甲基纤维素及丙烯酸酯类。

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。
