Study on Polypropylene - Acrylic Block Copolymers as Additives in UV Curable Coatings

摘要

Polypropylene - acrylic block copolymers have been developed for additives in UV curable coatings which give excellent adhesion to polypropylene substrates. In this study the factors affecting the coating performance properties have been investigated. The results show that the balance of the compatibility and the adhesion to polypropylene substrates is achieved through controlling the melting temperature, the molecular weight and the chemical structure of the block copolymers.
