    • The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.
    • 本发明涉及可以含有表面活性剂,杀生物剂和/或氧化剂的缔合性聚电解质配合物(PEC)的含水组合物,其可以为经处理的制品提供表面保护,包括减少污染趋势,降低清洁力和改善污垢排斥性,以及 为处理过的表面提供抑菌特性,从而获得对水的抗性,环境暴露和微生物的攻击。 提供了处理装置和组合物,其使用通过将水溶性阳离子第一聚电解质与具有相反电荷的水溶性第二聚电解质承载基团与第一聚电解质组合而形成的缔合聚电解质复合物,其中在其中加入以摩尔过量存在的一种聚电解质 在混合步骤期间第一水溶液的形式包含摩尔不足存在的相反电荷的聚电解质的第二水溶液。 还提供了在具有约0.10至20的R值的水溶液中形成稳定的缔合聚电解质络合物的方法,包括接近化学计量的R值接近1,即所用组分聚电解质上存在的带电基团的比例。
