用于护发产品的新一代阳离子调理聚合物

爱美高公司研制推出了新一代的SoftCAT^TM SL阳离子调理聚合物。SoftCAT^TM SL调理聚合物（INCI命名：聚季铵盐-67）是一系列高黏度、以三甲基胺和月桂基二甲基胺阳离子取代的季铵化羟乙基纤维素。这种新型的聚合物能够提供强化的美感和良好的相容性,不会产生缔合增稠现象。在透明香波和含硅油的二合一香波中评估该聚合物,并与市售的聚合物,如高分子质量低电荷密度的UCARE^TM LR-30M（INCI命名：聚季铵盐-10）和瓜尔羟丙基三甲基氯化铵进行比较。评估的性能参数有湿梳性、湿感、硅油吸附和累积现象。聚季铵盐-67在香波评估中表现出优异的湿梳理和干梳理性,对不同发质有优良的触感,并帮助硅油吸附。此外,它们还保留了聚季铵盐-10结构原型的其他优良性能,如可以形成完全透明的产品及没有累积现象等。这些聚合物无论含和不含硅油都可以作为不同表面活性剂体系中的有效调理剂。     

高分子质量聚氧化乙烯(PEO)和阳离子纤维素聚合物对于护发产品调理性能的协同效应

洗发体系中，同时使用高分子量聚氧化乙烯(PEO)和阳离子羟乙基纤维素(HEC)可以提供卓越的调理性能。用含有阳离子HEC和高分子量PEO的配方清洁头发，湿梳理性比仅含阳离子HEC的配方改善30％。与PEO结合使用，阳离子HEC控制的硅油和甲氧基肉桂酸辛酯(OMC)的吸附量分别有27％和25％的提高。极化显微镜观察发现，已稀释配方中聚合物一表面活性剂络合物(凝聚物的外观)在PEO存在时发生变化。含有PEO和阳离子HEC的配方，凝聚物的粒径更细小。这些结果表明：PEO阻止凝聚物聚集，以减小吸附颗粒大小。表面分析也显示：含有阳离子HEC的配方中存在PEO时，不溶性活性物在头发表面的吸附更加均匀。

Cationic UV cure kinetics for multifunctional epoxies

Two epoxy monomers with widely different functionalities (f = 2 and f = 8) were selected for the study and comparison of photocuring kinetics, in the presence of two different photoinitiators. It has been observed that for the same photoinitiator, the optimum concentration is lower for the epoxy monomer with a lower functionality. In terms of photoinitiation efficiency, the photoinitiator based on aromatic sulfonium salts has been determined to be a better candidate. © 2002 Wiley Periodicals, Inc.

Novel modified cellulosic polymers as drilling fluid additives with improved properties

Novel modified cellulosic polymers with amphoteric character were prepared by grafting 2-dimethylaminoethyl methacrylate (DM) and 4-vinylbenzene sulphonic acid sodium salt (VB) onto sodium carboxymethylcellulose (NaCMC), and characterized by IR and composition analyses. Their properties as drilling-fluid additives in oilfields were investigated with respect to shale inhibition, filtration control and viscosity enhancement. It is found that the grafting of DM enhances the shale-inhibition effectiveness and that the grafting of VB increases the tolerances to salt and temperature. Different from commonly used anionic and cationic polymeric additives, the modified cellulosic polymer with suitable structural parameters has both good shale-inhibition and mud properties. © 1999 Society of Chemical Industry

Polyurethane macromers—new building blocks for acrylic hybrid emulsions with outstanding performance

Emulsion polymerization is an efficient process to produce waterborne binders. It has been observed that films prepared from traditional latices do not show high performance especially concerning humidity and stone chip resistance. Polymeric emulsifiers are promising alternatives to low molecular weight surfactants. Polyurethanes are an interesting polymer class. The structure of the polymer backbone can be varied in a wide range by using different building blocks. The synthesis of copolymerizable polyurethanes, which have an amphiphilic structure similar to traditional surfactants, and their use in aqueous polymerization is discussed in detail. This process leads to polymer emulsions with structured particle morphology. The resulting films show outstanding properties. The polyurethane–polyacrylic dispersions can be used as binders for high performance waterborne coating formulations.     

Fibrillation tendency of cellulosic fibers,part 6: Effects of treatments with additive polymers

The influences of the treatments with various polymers on fibrillation and abrasion resistances of lyocell materials were investigated with respect to the type of polymer, the polymer concentration, and the drying temperature. Fibril number, generated with agitation using ball‐bearings (FN_ball), was decreased with increasing the concentration of aminofunctional polysiloxane because of reduction in water retention capacity (WRV) in fibers. The never‐dried lyocell fiber showed smaller decrease in FN_ball because of its higher WRV when compared to dried fibers. The treatment with aminofunctional polysiloxane enhanced not only the fibrillation resistance but also abrasion resistance, which was indicated as rotation number of abrasive bar in the abrasion test (RN_abr). No fibrillation was obtained in the fiber treated with 10 g/L aminofunctional polysiloxane at 120°C for 20 min, while the fibers treated at 60 and 170°C for 15 min were fibrillated in the agitation and abrasion tests. The addition of secondary polyethylene derivative also reduced the fibrillation tendency of lyocell; however, the extent of the reduction was lesser when compared with aminofunctional polysiloxane. The treatments with polyacrylate, polyurethane, and polyisocyanate derivatives improved the fibrillation resistance in lyocell fabrics, while fiber abrasion resistance was not significantly improved by the treatment with those additives, except in polyisocyanate. © 2006 Wiley Periodicals, Inc.
