Abstract
A blow-molded article contains a reaction product of a poly(3-hydroxyalkanoate) resin component and an organic peroxide. The resin component contains a copolymer (A) which is a copolymer of 3-hydroxybutyrate units and other hydroxyalkanoate units and in which the content of the other hydroxyalkanoate units is from 1 to 6 mol % and a copolymer (B) which is a copolymer of 3-hydroxybutyrate units and other hydroxyalkanoate units and in which the content of the other hydroxyalkanoate units is 24 mol % or more. In the resin component, the proportion of the copolymer (A) is from 30 to 70 wt % and the proportion of the copolymer (B) is from 30 to 70 wt %. The amount of the organic peroxide is from 0.01 to 0.8 parts by weight per 100 parts by weight of the resin component.
Claims15
A blow-molded article comprising:
- a reaction product of a poly(3-hydroxyalkanoate) resin component and an organic peroxide, wherein
- the poly(3-hydroxyalkanoate) resin component comprises
- a copolymer (A) which is a copolymer of 3-hydroxybutyrate units and one type of other hydroxyalkanoate units or two or more different types of other hydroxyalkanoate units and in which a content of all of the other hydroxyalkanoate units is from 1 to 6 mol % based on the total content of units in the copolymer (A), and
- a copolymer (B) which is a copolymer of 3-hydroxybutyrate units and one type of other hydroxyalkanoate units or two or more different types of other hydroxyalkanoate units and in which a content of all of the other hydroxyalkanoate units is at least 24 mol % based on the total content of units in the copolymer (B),
- in the poly(3-hydroxyalkanoate) resin component, a proportion of the copolymer (A) is from 30 to 70 wt % and a proportion of the copolymer (B) is from 30 to 70 wt %, and
- an amount of the organic peroxide is from 0.01 to 0.8 parts by weight per 100 parts by weight of the poly(3-hydroxyalkanoate) resin component.
