Patent ID: 6911520

Claim:
A polyhydroxyalkanoate containing in a molecule thereof one or more units each selected from the group consisting of the following formulae (1), (2), (3) and (4): wherein R 1 is selected from the group consisting of OH, a halogen atom, ONa, OK, OCH 3 and OC 2 H 5 ; A 1 represents a substituted or unsubstituted aliphatic hydrocarbon structure; m is an integer selected from 0 to 7; and in the case where there exists a plurality of units, R 1 , A 1 and m represent the above described definements independently for each unit, wherein R 6 is selected from the group consisting of OH, a halogen atom, ONa, OK, OCH 3 and OC 2 H 5 ; J 6 represents a substituted or unsubstituted aliphatic hydrocarbon structure; n is an integer selected from 0 to 7; r is an integer selected from 1 to 500; and in the case where there exists a plurality of units, R 6 , J 6 , n and r represent the above described definements independently for each unit, wherein n represents an integer of 0 to 7; and n represents the above described definements independently for each unit, and wherein m represents an integer of 0 to 7; R 1 ′ to R 5 ′ represent independently H or a halogen atom; and in the case where there exists a plurality of units, m and R 1 ′ to R 5 ′ represent the above described definements independently for each unit.
