FUNCTIONAL AGENT BONDED TO POLYMER, ITS PRODUCTION, ITS USE AND ARTICLE USING THE AGENT

摘要

PROBLEM TO BE SOLVED: To obtain the subject functional agent having excellent compatibility with various synthetic resins, etc., excellent processability, heat stability, bleed resistance, etc., useful as an antioxidant, etc., by reacting a specific functional agent with a specified polymer. SOLUTION: A functional agent containing a reactive group [e.g. 3-(3',5'-di-t- butyl-4'-hydroxyphenyl)propionic acid] is reacted with a polymer containing a group to be reacted with the reactive group to give the objective functional agent being an antioxidant, ultraviolet light absorber, light stabilizer, infrared light absorber and/or antistatic agent. Preferably the reaction temperature is generally 80 deg.C to the boiling point of a reaction solvent and the reaction time is generally 2-10 hours. The polymer part is preferably at least one kind selected from the group consisting of a polyolefin-based polymer, a polyether- based polymer, a polyester-based polymer, etc. The reaction is preferably a condensation reaction between a hydroxyl group and a carboxyl group or carboxyl chloride.
