Abstract

A biodegradable test kit and a method for making a biodegradable test kit. The biodegradable test kit includes a first molded body section and a second molded body section configured to be attached to the first molded body section for holding a test strip between the first molded body section and second molded body section, wherein the first and second molded body sections comprise from about 50 to about 99.5 weight percent poly hydroxyalkanoate.

Claims (17)

1 . A biodegradable test kit comprising a first molded body section and a second molded body section configured to be attached to the first molded body section for holding a test strip between the first molded body section and second molded body section, wherein the first and the second molded body section are composed of a material that comprises between 50 weight percent to 99.5 weight percent polyhydroxyalkanoate.

2 . The biodegradable test kit of claim 1 , wherein the polyhydroxyalkanoate is selected from the group consisting of homopolymer, a copolymer, a terpolymer, and mixtures thereof of a hydroxyalkanoate.

3 . The biodegradable test kit of claim 1 , wherein the polyhydroxyalkanoate comprises poly-3-hydroxybutyrate-co-3-hydroxyhexanoate.

4 . The biodegradable test kit of claim 1 , wherein the polyhydroxyalkanoate comprises a terpolymer made up from about 75 mole percent to about 99.9 mole percent monomer residues of 3-hydroxybutyrate, from about 0.1 mole percent to about 25 mole percent monomer residues of 3-hydroxyhexanoate, and from about 0.1 mole percent to about 25 mole percent monomer residues of a 3-hydoxyalkanoate having from 5 to 12 carbon atoms, where the first molded body section and the second molded body section are biodegradable as determined by ASTM D5988.

5 . The biodegradable test kit of claim 1 , where the first molded body section and the second molded body section are composed of a material that comprises a major amount of the polyhydroxyalkanoate and a minor amount of one or more additional biodegradable polymers selected from the group consisting of polycaprolactone, polylactic acid, polybutylene succinate, polybutylene succinate-co-butylene adipate, polybutylene adipate terephthalate, other biodegradable polymers, and mixtures thereof.

6 . (canceled)

7 . A method for making a biodegradable test kit comprising molding first and second body sections of the biodegradable test kit from about 50 to about 99.5 weight percent polyhydroxyalkanoate;

attaching a test indicator strip to one of the first body section and the second body sections, and

attaching the first and second body sections to one another so that the test strip is between the first body section and the second body section.

8 . The method of claim 7 , wherein the polyhydroxyalkanoate is selected from the group consisting of homopolymer, a copolymer, a terpolymer, and mixtures thereof of a hydroxyalkanoate.

9 . The method of claim 7 , wherein the polyhydroxyalkanoate comprises poly-3-hydroxybutyrate-co-3-hydroxyhexanoate.

10 . The method of claim 7 , wherein the polyhydroxyalkanoate comprises a terpolymer made up from about 75 to about 99.9 mole percent monomer residues of 3-hydroxybutyrate, from about 0.1 to about 25 mole percent monomer residues of 3-hydroxyhexanoate, and from about 0.1 to about 25 mole percent monomer residues of a third 3-hydoxyalkanoate having from 5 to 12 carbon atoms.

11 . The method of claim 7 , where the first and second body sections comprise a major amount of polyhydroxyalkanoate and a minor amount of one or more additional biodegradable polymers selected from the group consisting of polycaprolactone, polylactic acid, polybutylene succinate, polybutylene succinate-co-butylene adipate, polybutylene adipate terephthalate, and mixtures thereof.
