Abstract
Official abstract text for this publication.
The present invention provides a vinyl alcohol-amino acid ester copolymer that is excellent in properties such as cell culture properties, biocompatibility, antibacterial properties, and solubility in organic solvents, and is applicable to the medical field, the biomaterial field, and the agricultural field (medical and life science fields). Provided is a vinyl alcohol-amino acid ester copolymer including a unit represented by the following formula (1) and a unit represented by the following formula (2): where, in the formula (2), R 1 represents a hydrocarbon group that may optionally have a substituent, R 2 and R 3 each independently represent a hydrogen atom or a hydrocarbon group, and R 1 and R 2 , or R 2 and R 3 , may optionally be bonded together to form a cyclic structure.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vinyl alcohol-amino acid ester copolymer comprising a unit represented by the following formula (1), a unit represented by the following formula (2) and a unit represented by the following formula (3): wherein, in the formula (2), R 1 is at least one group selected from the group consisting of a C1-C20 linear or branched alkylene group having a phenol substituent and a C1-C20 linear or branched alkylene group having a C2-C20 alkoxycarbonyl substituent, wherein the phenol substituent is hydroxyphenyl, R 2 and R 3 each independently represent a hydrogen atom or a hydrocarbon group, and R 1 and R 2 , or R 2 and R 3 , may optionally be bonded together to form a cyclic structure; and wherein, in the formula (3), R 4 represents a hydrogen atom or a C1-C20 alkyl group. 2. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein the content of the unit represented by the formula (1) is 0.1 to 99.5 mol %. 3. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein the content of the unit represented by the formula (2) is 0.1 to 99.5 mol %. 4. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein the content of the unit represented by the formula (3) is 0.5 to 90 mol %. 5. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein, in the unit represented by the formula (2), R 2 and R 3 each represent a hydrogen atom or an alkyl group. 6. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein, in the formula (3), R 4 represents a C1-C20 alkyl group. 7. The vinyl alcohol-amino acid ester copolymer according to claim 1 , wherein, in the formula (3), R 4 represents an n-propyl group.
