| titleOfInvention | Method for purifying siloxane containing hydroxyl group and (meth)acrylic group, and siloxane composition containing hydroxyl group and (meth)acrylic group |
| abstract | An object of the present invention is to provide a method for producing a siloxane containing hydroxyl groups and (meth)acrylic groups with high purity and high yield. Kind Code: A1 A mixture containing a (meth)acrylic group-containing siloxane represented by the following formula (I) and an impurity derived from the siloxane and/or a raw material compound of the siloxane is added in one molecule. Purification of the (meth)acrylic group-containing siloxane, comprising the step of removing the impurities by distillation under reduced pressure in the presence of a polymerization inhibitor having at least one nitroxyl radical and having a molecular weight of 160 to 2,000. provide a way. (Wherein, R 'is a hydrogen atom or a methyl group, L is a divalent hydrocarbon group that has at least one hydroxyl group and may have an ether bond, and A is an organo(poly)siloxane residue. be) [Selection figure] None |
