| titleOfInvention | Aliphatic polycarbonate |
| abstract | An object of this invention is to find a method for introducing a functional group into an aliphatic polycarbonate without impairing the excellent thermal decomposition property of the aliphatic polycarbonate. n An aliphatic polycarbonate comprising a constituent unit represented by formula (1): n n n n n n n n n n wherein R 1 , R 2 , and R 3 are identical or different, and each represents a hydrogen atom, a C 1-10 alkyl group optionally substituted with one or more substituents, or a C 6-20 aryl group optionally substituted with one or more substituents, wherein two groups from among R 1 to R 3 , taken together with the carbon atom or carbon atoms to which these groups are attached, may form a substituted or unsubstituted, saturated or unsaturated 3- to 10-membered aliphatic ring; and X represents a divalent group containing one or more heteroatoms or an alkylene group having 3 or more carbon atoms, andn a constituent unit represented by formula (2): nn n n n n n n n n n wherein R 4 , R 5 , R 6 , and R 7 are identical or different, and each represents a hydrogen atom, a C 1-10 alkyl group optionally substituted with one or more substituents, or a C 6-20 aryl group optionally substituted with one or more substituents, wherein two groups from among R 4 to R 7 , taken together with the carbon atom or carbon atoms to which these groups are attached, may form a substituted or unsubstituted, saturated or unsaturated 3- to 10-membered aliphatic ring,n the content of the constituent unit represented by formula (1) being 0.1 mol % or more and 1.5 mol % or less, based on the total amount of the constituent units of formula (1) and formula (2). |
