Title:
POLYMER, METHOD FOR PURIFYING THE SAME, FINE PARTICLE DISPERSION BY USING THE POLYMER, AND THERMALLY DEVELOPING PHOTOSENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JP2008260792
Kind Code:
A
Abstract:
To provide a method of purification, capable of efficiently removing low molecular weight components such as a residual monomer, oligomers, etc., from an amphiphilic copolymer.
The polymer formed by polymerizing a monomer expressed by general formula (1) and a monomer expressed by general formula (2) is purified by using a 3-component solvent system consisting of water, an alcoholic solvent and an organic solvent having 14.0 to 21.0 [(MPa)1/2] solubility parameter (SP value).
