Novel lactone-modified polyvinyl, acetal resin, process for the preparation thereof, curable resin composition, and a magnetic recording medium. |
摘要 |
<p>A novel lactone-modified polyvinyl acetal resin and a novel carboxyl-modified resin thereof are disclosed. The novel resins of the present invention can be used as a polyol resin for coatings curable at ordinary temperatures or heating, adhesives, binders, a processing agent for fibers, a curable resin composition by mixing with a curing agent which can react to hydroxyl groups, and a composition for a magnetic recording medium, etc. The novel resins of the present invention have graft chains containing primary hydroxyl groups bonded to the ester group derived from a lactone compound, or the primary hydroxyl groups and carboxylic groups. <IMAGE></p> |
