Abstract
A vinyl ether compound represented by formula (1-a) or formula (1-b): wherein n represents 0 or 1, and R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2.
Claims15
A vinyl ether compound represented by formula (1-a) or formula (1-b):
- wherein n represents 0 or 1, and R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2.
A vinyl ether polymer comprising a structural unit represented by formula (2-a) and/or a structural unit represented by formula (2-b):
- wherein n represents 0 or 1, and R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2.
A method for producing a vinyl ether compound, comprising:
- a first step of hydrolyzing a compound obtained by reaction of a norbornene compound represented by formula (4) with a carboxylic acid represented by formula (5) in the presence of an acid catalyst, to obtain a norbornanol compound represented by formula (6-a) or formula (6-b);
- and
- a second step of vinylating a hydroxyl group of the norbornanol compound to obtain a vinyl ether compound represented by formula (1-c) or formula (1-d),
- wherein R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2,
- [Chemical Formula 5]
- R5—CO2H (5)
- wherein R5 represents an alkyl group having 1 to 20 carbon atoms,
- wherein R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2,
- wherein R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2.
