Abstract
Methods of reducing exposure to latex comprise forming an item comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units. The first randomly repeating monomer unit has the structure: 1 wherein R1 is H, or C1-2 alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure: 2 wherein R2 is a C3-19 alkyl or C3-19 alkenyl. At least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
Claims21
A method of reducing exposure to latex comprising forming an item adapted for contact with a human or animal body or component thereof, of a material comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure:
- 25
- wherein R1 is H, or C1-2 alkyl, and n is 1 or 2;
- and the second randomly repeating monomer unit has the structure:
- 26
- wherein R2 is a C3-19 alkyl or C3-19 alkenyl;
- and wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
A method of reducing exposure to plasticizers comprising forming an item adapted for contact with a human or animal body or component thereof, of a material comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure:
- 28
- wherein R1 is H, or C1-2 alkyl, and n is 1 or 2;
- and the second randomly repeating monomer unit has the structure:
- 29
- wherein R2 is a C3-19 alkyl or C3-19 alkenyl;
- and wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
A non-latex-allergenic item adapted for contact with a human or animal body or component thereof, of a material comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure:
- 31
- wherein R1 is H, or C1-2 alkyl, and n is 1 or 2;
- and the second randomly repeating monomer unit has the structure:
- 32
- wherein R2 is a C3-19 alkyl or C3-19 alkenyl;
- and wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit, and further wherein the item in substantially free of latex.
