Abstract

Compositions of PHAs with PBS and/or PBSA are described and methods of making the same.

Claims (16)

1. A composition, comprising:

a blend of a first component and a second component,

wherein the first component includes a poly(butylene succinate) (PBS) or a polybutylene succinate adipate (PBSA), and the second component includes a polyhydroxyalkanoate (PHA),

wherein the content of the first component in the composition is 50% or greater by weight, wherein the second component is selected from a group consisting of a homopolymer or a copolymer of a 3-hydroxyalkanoate, a homopolymer or a copolymer of 4-hydroxyalkanoate, and a homopolymer or a copolymer of a 5-hydroxyalkanoate.

2. The composition of claim 1 , wherein the blend of a first component and a second component is an unreacted blend.

3. The composition of claim 1 , wherein the content of the first component in the composition is between 50% and 80% by weight.

4. The composition of claim 3 , wherein the content of the first component in the composition is between 50% and 65% by weight.

5. The composition of claim 1 , wherein the PHA is a PHA copolymer.

6. The composition of claim 1 , wherein the PHA copolymer is a copolymer of a 3-hydroxybutyrate (PHB copolymer).

7. The composition of claim 6 , wherein the PHA copolymer is a Type 1 PHB copolymer.

8. The composition of claim 6 , wherein the PHA copolymer is a Type 2 PHB copolymer.

9. The composition of claim 6 , wherein the PHA copolymer is a copolymer of a poly(3-hydroxybutyrate-co-3-hydroxypropionate), a poly(3-hydroxybutyrate-co-4-hydroxybutyrate), a poly(3-hydroxybutyrate-co-4-hydroxyvalerate), a poly(3-hydroxybutyrate-co-3-hydroxyvalerate), a poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), or a poly(3-hydroxybutyrate-co-5-hydroxyvalerate).

10. The composition of claim 1 , wherein the second component PHA is a PHA homopolymer.

11. The composition of claim 10 , wherein the PHA homopolymer is a poly(3-hydroxybutyrate).

12. An article, comprising the composition of claim 1 .

13. The article of claim 12 , wherein the article is a film.
