1,4-부탄디올로부터 유도되는 반복 단위로 구성된 폴리에스테르의 탈기(outgassing)를 감소시키기 위한 방법은 폴리에스테르를 폴리에스테르의 중량을 기준으로 0.2 내지 2 중량%의 물과 용융 블렌딩하는 것이다. 물에 더하여, 폴리에스테르는 또한 0.01 내지 0.5 중량%의 켄처(quencher)와 블렌딩될 수 있다. 본 방법은, 탈기가 감소되고, 물품, 예를 들어 자동차 헤드라이트 반사경 또는 베젤(bezel)로 성형하기에 적합한 폴리에스테르 조성물의 형성을 가져온다.
A method for reducing outgassing of a polyester composed of repeat units derived from 1,4-butanediol is melt blending the polyester with 0.2 to 2 weight percent water, based on the weight of the polyester. In addition to water, the polyester can also be blended with 0.01 to 0.5 weight percent of a quencher. The method results in formation of a polyester composition which exhibits reduced outgassing, and is suitable for molding into articles, for example an automotive headlight reflector or bezel.
