ABSTRACT:
Highly adherent release compositions having very low surface tensions comprise a polymer containing a pendant benzyl portion linked through a benzyl ester linkage to a perfluorocarbon moiety. Such compositions will not wet with any common solvents. Such compositions are most advantageously employed as release coatings on internal surfaces of molding apparatus.
