Abstract: A method for producing PHA polymer includes using bacteria in which the bacteria are grown under heterotrophic conditions using an organic substance as carbon source and exponential growth conditions. The bacteria are then cultivated under autotrophic conditions under an atmosphere of H2, CO2 and O2, wherein the O2 content is less than 10% (v/v) and the pressure is more than 1 barg.

Abstract: A polyhydroxyalkanoate composition, having a an elongation at break (ASTM D648) greater than 3%, an impact resistance (IS0179 1 eA, 23° C., unnotched) greater than 18 KJ/m2 and a flexural modulus of at least 950 MPa, includes at least 25% wt of a polyhydroxyalkanoate component (I); from 5 to 40% wt of one or more thermoplastic polymers as a non-polyhydroxyalkanoate component (II); from 0 to 40% wt of one or more fillers (III); from 0 to 20% wt of one or more plasticizers (IV); and from 0 to 10% wt of one or more additives (V). The polyhydroxyalkanoate composition can be used for the preparation of durable goods that may be labelled as containing more than 20% non-fossil carbon, and for articles prepared therefrom.

Abstract: A thermofusible composition comprising from about 40 to about 70 weight percent of a selectively hydrogenated styrenic block copolymer (HSBC), and from about 1 to about 30 weight percent of a butylene homopolymer, a butylenes copolymer, or a combination thereof, wherein the HSBC is: (i) prior to hydrogenation each A block is a mono alkenyl arene polymer block and each B block is a controlled distribution copolymer block of at least one conjugated diene and at least one mono alkenyl arene; (ii) the weight percent of mono alkenyl arene in each B block is from about 10 to about 40 weight percent; (iii) each B block has a styrene blockiness index of less than 10 percent; and (iv) the weight percent of vinyl in each B block is at least about 40 weight percent.
