Method for the emulsification of asa with polyamidoamine epihalohydrin (pae)

The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.

ANTIBACTERIAL POLYMER AND PREPARATION METHOD THEREOF

An antibacterial polymer and a preparation method thereof are provided. The antibacterial polymer is obtained by polymerization of a polyol and a guanidine salt, and has the following structure: The present application relates to the field of organic synthesis and environmental protection. Specifically, the present application provides an antibacterial polymer formed by polymerization of a non-toxic/non-irritating polyol and a guanidine salt and a preparation method of the antibacterial polymer.Compared with natural materials, chemical materials such as plastics and chemical fibers have the advantages of long life, stable properties, simple manufacture, light weight, and non-hygroscopicity. Therefore, they become regular raw materials for the manufacture of various daily supplies and clothing. The above-mentioned chemical materials are commonly used in bathrooms, kitchens, bags, clothing, etc., where they are relatively rich in humidity, heat, and organic matter, thus forming an environment that microorganisms are easy to breed. Therefore, it is often necessary to add antibacterial agents to these materials to form antibacterial materials.Among the commonly used plastic antibacterial agents, natural antibacterial agents cannot be widely used due to price and stability. Inorganic antibacterial agents are mainly metal ions such as silver ions and zinc ions supported on zeolite, such that the resulting products are often unstable in performance due to the complex preparation process, and often have defects in anti-fungal properties. Organic antibacterial agents mainly include quaternary ammonium salts, ethers, phenols, thiazoles, diphenyl ether compounds, etc., and have fast sterilization speed and broad antibacterial spectrum, but their heat and water resistance and chemical resistance are poor, such that the resulting product has a short antibacterial validity period. The above-mentioned problems are particularly noticeable when such organic antibacterial agents are ...
