압출 및 사출 가공에 사용되는 재료인 열가소성 폴리우레탄(TPU, Thermoplastic Polyurethane) 탄성체를 합성하고, 물성을 비교하는 실험 을 진행하였다. 공업적으로 사용되는 polyester polyol은 벤젠을 출발물질로 하는 adipic acid와 phthalic acid 및 각종 glycol을 병용하여 제조된다. 최근에 biomass 유래 building block이 개발되어, 각종 glycol에 적용되기 시작했 다. 대표적인 building block으로 azelaic acid, sebacic acid, succinic acid 와 같은 dicarboxylic aicd 류, 1,4-butanediol, 1,3-propanediol, isosorbide 와 같은 diol 류가 있다. 본 연구에서는 azelaic acid, sebacic acid, succinic acid와 1,3-propanediol, isosorbide를 원료로 하여 polyester polyol을 축중합하였 다. 이어서 isocyanate는 MDI(4,4’-methylenebis(phenyl isocyanate)), chain extender는 1,4-butanediol, 1,3-propanediol, isosorbide를 사용하여 TPU를 합성하였다. 그리고 acid 종류, chain extender 종류, isocyanate 함량에 따른 TPU의 물성 변화를 비교, 분석하였다.

The thermoplastic polyurethane(TPU) materials, which are applied to extrusion and injection processing, were synthesized as elastomers, and their mechanical properties had been also compared and studied in this research. In the industry field, the polyester polyols are always synthesized by adipic acid or phthalic acid which have benzene structure in their molecular and various glycols. Recently, with the development of biomass building blocks, biomass has been applied to produce the raw materials of polyester polyols. More representative building blocks: dicarboxylic acid, like azelaic acid, sebacic acid and succinic acid, and diol materials like 1,4-butanediol, 1,3-propanediol and isosorbide. In this research, the biomass polyester polyols were synthesized by azelaic acid, sebacic acid, succinic acid, 1,3-propanediol and isosorbide by different ratios. Then mixed with isocyanate (4,4’-methylenebis (phenyl isocyanate) (MDI)) and chain extender (1,4-butanediol, 1,3-propanediol, and isosorbide) to produce the TPU. After that, the analysis and comparative work of different TPU samples had been carried out according to the different types of acid, types of chain extender and ratios of isocyanate.
