Development and Application of Acrylic Telechelic Polymers for Functionalized Pressure Sensitive Adhesives

Abstract

We synthesized acrylic telechelic polymers having hydroxy groups at both ends by living radical polymerization method. Adding a suitable polyisocyanate to these polymers, characteristic adhesives that formed chain elongation structure and cross linking structure were provided. The adhesive per_ formances of these adhesives were equal to existing product. And furthermore, these adhesives showed low contamination for adherend after the heat resistance test, and low temperature dependency and release rate dependency of the adhesive strength. Depending on composition, volatilization of adhesives was able to assume the high solid content more than 80%.
