According to Q-e equation, EMA and iPMA that are prone to copolymerize with NIPAM were selected to prepare hydrophobically-modified pNIPAM microgels.

根据Q-e方程，通过选择易于与NIPAM共聚的疏水性单体EMA、iPMA，成功制备了疏水性链段在微凝胶网络中无规分布的疏水改性pNIPAM微凝胶。

Cation group has the capability of charge neutrality and this would make oily wastewater demulsify and remove oil easily. Hydrophobic group would improve hydrophobic-oleophilic nature of the oil granule. Simultaneously, wetting reversed agent would change wetting performance of oil granule, enhance conglutination capability between air bubble and oil granule. And Frother would form bigger foam layer on the water, so it could prevnt granule with air bubble from rolling downward.Using the hydrophobic polymeric flocculant as one of ingredients for flotation agent formula, the flotation agent has good treatment effect.

The influences of the concentration and generation of polyamidoamine dendrimer, the ratio of dodecanoic acid to toluene, and pH in the water phase on the extraction yield of helianthine were systematically studied by selecting helianthine as the guest molecule and electrostatic self-assembled PAMAM as the host.

本文采用低支化树枝状大分子聚酰胺胺与月桂酸进行分子自组装得到了一系列具有稠密的疏水性外围和亲水性内核的自组装大分子，再以自组装大分子为宿主，系统地研究了树枝状大分子聚酰胺胺的浓度、支化代、月桂酸与甲苯的质量比及水相pH值对客体分子甲基橙相转移行为的影响规律。

Water-based ink primarily use anti－alkali ensuer aqueous and dispersancy good organic or inorganic pigments, which in addition to the ordinary powdered pigments, pigment dispersion filter cake, pigments and dispersion of water in the paint.

水性油墨主要使用耐碱性强、在水体系中分散性好的有机或无机颜料，这些颜料除普通的粉末状外，还有颜料滤饼、颜料水性分散体及水中易分散颜料。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.
