Abstract
Butyl acrylate, methyl methacrylate, vinyl acetate and tertiary vinyl carbonate (VeoVa10) are the main monomers, and alkyl alcohol polyether sulfosuccinate monoester sodium salt (A-6820) and alkyl alcohol polyoxyethylene ether (EFS-900) are used as the emulsifiers. Vinyl triethoxysilane is used as the modified monomers. Potassium persulfate is the initiator. The silicon-modified polymer latex is prepared via the semi-continuous seeded emulsion polymerization. The structure of the latex film is characterized by Fourier transform infrared spectroscopy. Latex films are tested by the thermogravimetric analysis, differential scanning calorimetry and contact angle. The particle size of the latex is measured with the zetatrac dynamic light scattering instrument. The conditions for preparing the resultant latex is optimized and obtained as follows: the amount of emulsifier is 6 wt%; the amount of initiator is 0.4 wt% and the amount of VETS is 4 wt%. The appearance of the resultant latex is translucent and blue, and the average particle size of the polymer latex and its distribution is small. The water contact angle increased from 68.07 to 91.00 °. Thermal decomposition temperature of the film of the silicone-modified polymer latex is 16.17 °C higher than that of the film of conventional polymer latex.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
