查询词典 latexes

With unique thermal property attributes, the interpolymer product is useful, for example, for impact, bitumen and asphalt modification, adhesives, dispersions or latexes and fabricated articles such as, but not limited to, foams, films, sheet, moldings, thermoforms, profiles and fibers.

由于其独特的热性质，该共聚体产生能用于，例如，抗冲材料、沥青及柏油的改性、粘合剂、分散液或胶乳及制备物件，比如，泡沫材料、膜、片材、模制品、热成形材料、型材及纤维，但不限于此。

TEM, FTIR, spectrophotometry characterized the morphology, structure and dispersion stability of nanoparticles respectively. The results show that the inorganic nanoparticles in the aqueous solution can redisperse more effectively through ultrasonic irradiation than by conventional stirring, which was the basis for monomers to polymerize on the surface of nanoparticles. By selecting proper nanoparticles and monomers, the long-stable latexes were successfully prepared.

研究了超声辐照下多种纳米粒子(SiO〓、Al〓O〓、TiO〓)在水体系中的分散、粉碎及活化等各种行为，采用TEM、FTIR、分光光度法等对纳米粒子的形态、结构、分散稳定性进行了表征，证明超声辐照比常规搅拌更有效地实现无机纳米粒子在液相中的分散，为单体在纳米粒子表面的聚合创造了条件。

In addition, other operation condition, such as soapless seeded preparation schedule or without seed, could meet the requirement of the larger particle sizes, broader particle sizes distribution and lower viscosities. Besides the increment of addition rate induces the peel strength and tack decreased and the holding power increased for the PSA tapes that are made from the multicopolymer latexes, the above operation conditions which lead the particle sizes to enlarge would increase the peel strength and tack, and decrease the holding power.

用多元共聚胶乳制备的压敏胶带，除单体滴加速率增加使剥离强度与初粘力下降、持粘力增加外，通常，使胶乳粒径变大的操作条件将使压敏胶剥离强度与初粘力增加，持粘力降低。

Ambient temperature self-crosslinking acrylic latexes were prepared through semicontinuous emulsion polymerization using 3 different polymerizable alkoxysilanes, i.e. vinyl tri silane (A172), Vinyl triethoxy silane and γ-methacryloxypropyl trimethoxy silane (A174). The hydrolysis of these siloxanes under different pH was characterized, and dependence of the latex and polymer properties on these siloxanes and their incorporated amounts in the polymers was studied.

使用三种含不饱和双键硅氧烷，乙烯基三硅烷(A172)、乙烯基三乙氧基硅烷和γ-甲基丙烯酰氧丙基三甲氧基硅烷(A174)为功能单体，采用半连续乳液聚合法制备了室温自交联丙烯酸酯乳液，探讨了硅氧烷功能单体在不同pH条件下水解情况以及其种类和用量对乳液及乳胶膜性能的影响。

The polymerization mechanism,the polymer molecule structure and the film forming properties of the latexes were also investigated.

同时对聚合反应的机理、产物的结构及胶膜性能作了考察。

This method is very important to prepare the stable latexes with high-solid content.

水溶性单体的存在易使胶乳不稳定，其主要原因是大量水相成核。

There is no-AOX pollution when the latexes were being prepared and used.

胶乳在制备和使用过程中不会对环境产生AOX污染。

A few methods for removal of residual monomer s from polymer latexes were reviewed.

综述了聚合物胶乳中残留单体的几种脱除方法。

Latexes are shown to be useful to study at atomic level the morphology of Sm-Co and Sm-Co-Zr alloys.

表明了在原子级别上用乳液来研究Sm-Co和Sm-Co-Zr合金的形态学是很有用的。

The invention also relates to redispersible powders which can be obtained by drying said latexes.
