시드중합에 의한 폴리우레탄 아크릴레이트 하이브리드 에멀젼의 합성 및 물성 = The Properties and Synthesis of Polyurethane Acrylate Hybrid Emulsion by Seeded Polymerization

다국어 초록 (Multilingual Abstract)

Polyurethane acrylate hybrid emulsions were prepared by seeded polymerization techniques. In the synthesis, seeded polyurethane dispersion containing carboxylic group was used to important hydrophilicity to the hybrid poly-urethane portions and various acrylate portains such as 2-hydroxy ethylmethacrylate (2-HEMA), n-butyl acrylate (n-BA) and acrylic acid (AAc). The weight ratio between acrylic and polyurethane components varied to obtain different emulsion properties, microphase structure, and mechanical film properties of hybrid emulsions. The tensile strength, 100% modulus, elongation and swelling properties of the polyurethane acrylate hybrid emulsion were studied and compared with those of polyurethane homopolymer and acrylate emulsion, respectively. And the mechanical and chemical properties of polyurethane acrylate hybrid emulsion with different glass transition temperature were studied.
