초록

Diacid로써 succinic acid를 사용하고 diol로써 1,6-hexanediol과 PDMS diol을 이용하여 축중합에 의해 주쇄내에 실록산 불럭이 도입된 지방족 폴리에스테르 공중합체인 poly(hexylene-co-PDMS succinate)를 합성하였다. 공중합체에 실록산 블록의 함량이 증가함에 따라 유리전이온도 및 결정의 용융 온도가 저하되었으며, 기계적 물성의 경우 인장강도는 감소하고 파단신율은 증가되었다. 공중합체 표면의 물에 대한 접촉각을 측정한 결과 공중합체에서 실록산의 함량이 증가할수록 접촉각이 증가하였다. X-ray photoelectron spectroscopy(ESCA)를 이용한 표면층의 원소분석결과 실록산 세그멘트가 표면층에 주로 존재함으로써, 표면의 소수성을 증가시킴을 알았다.

Poly(hexylene-co-PDMS succinate), aliphatic copolyesters containing siloxane block, were synthesized by a condensation polymerization using 1,6-hexanediol and hydroxy terminated polydimethylsiloxane as diols and succinic acid as dibasic acid. As siloxane content in the copolymer increased, glass transition temperature and melting temperature of the copolyesters were reduced. And, with the increase in the siloxane content in the copolymers, there was a decrease in tensile strength and increase in elongation at break. Contact angle against water indicated that as the PDMS content in the copolymer was increased, hydrophobicity of the surface of the copolyesters increased. ESCA results indicated that PDMS segments were predominating at the outer surface of the copolyesters.

Keywords:siloxane block;aliphatic polyester;condensation polymerization;contact angle;ESCA
