| Summary: | 碩士 === 國立臺灣科技大學 === 高分子系 === 95 === The study mainly discusses the characters of the composing and physics on the process of Acrylic/WPU latex Hybrid production by changing and adding different types of Acrylic such as methylmethacrylate and butyl acrylate in different proportion.
The study focuses on that the m-TMXDI base anionic polyurethane dispersion which are synthesized by prepolymer mixing process are composed of the latex with different proportion by Hybrid production of adding different types of Acrylic:methylmethacrylate, butyl acrylate, and changing the structure of Acrylic with GPC, FTIR, TGA, DLS. According to the results of the research, after WPU/Acrylic are synthesized, they has not only more powerful affect on hard segment, but also better increase on particle size and heat-resistant when MPU is synthesized by mixing MMA and BA. Moreover, they are more probably to increase the structure of the core- shell during the process of hydrophobic Acrylic polymerization.
The study emphasizes that the m-TMXDI base anionic polyurethane dispersion which are synthesized by prepolymer mixing process are composed of the latex with different proportion by Hybrid production of adding different types of Acrylic: methylmethacrylate and butyl acrylate, analyzes the types, mechanical characters, surface and section of different kinds of the panniculus after it is made in the condition of the vaccum and aridity, and uses Dynamic Mechanical Analysis to realize the effect on molecule. The mechanical characters are measured by the curve of stress and strain, and the analysis of the surface and section is observed by Scanning Electron Microscope. The experimental results show that adding MMA and BA in approximate proportion can gain the mechanical characters efficiently, and DMA can be found that the model of the deposition is increased corresponsively. The unglue and irregularity of the surface and section can add BA to get better characters.
