Abstract
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.
