Alkyl-modified vinyl acetal polymer, and composition
Provided are a vinyl acetal polymer that has sufficient plasticity and solubility in an alcohol solvent, imparts low viscosity, stability, etc., to a solution thereof, is less likely to cause phase separation from other components, and allows for formation of a slurry superior in dispersibility of particles and thixotropic nature, as well as a sheet superior in strength and flexibility, and the like. An alkyl-modified vinyl acetal polymer obtained by subjecting an alkyl-modified vinyl alcohol polymer to acetalization, in which the alkyl-modified vinyl alcohol polymer comprises a monomer unit represented by the following general formula (I), and has a viscosity average degree of polymerization P of 150 or greater and 5,000 or less, a degree of saponification of 20 mol % or greater and 99.99 mol % or less, and a percentage of alkyl modification S with the monomer unit of 0.05 mol % or greater and 5 mol % or less.
