바이모달 분자량 분포를 갖는 폴리(히드록시알카노에이트) 조성물 조성물은 폴리(히드록시알카노에이트) 의 제 1 부분 및 제 2 부분을 포함한다. 제 1 부분은 제 1 중량 평균 분자량을 갖고, 제 2 부분은 제 1 중량 평균 분자량보다 적어도 50% 적은 제 2 중량 평균 분자량을 갖는다. 폴리(히드록시알카노에이트) 는 3-히드록시프로피오네이트의 단량체 반복 단위 적어도 10 몰% 로 구성된다. 조성물의 제조 방법이 또한 기재된다. A poly(hydroxyalkanoate) composition having a bimodal molecular weight distribution. The composition includes of a first portion and a second portion of a poly(hydroxyalkanoate). The first portion has a first weight average molecular weight and the second portion has a second weight average molecular weight which is at least 50 percent less than the first weight average molecular weight. The poly(hydroxyalkanoate) is made up of at least 10 mole percent monomer repeat units of 3-hydroxypropionate. A method for making the composition is also disclosed.
