ABSTRACT:
Novel polymers and prepolymers are formed by reacting a fluorinated terti polyfunctional alcohol with an aliphatic diisocyanate or a biuret derivative of said diisocyanate in the presence of a suitable catalyst and in the absence of solvent. The novel polymers and prepolymers exhibit low surface energy properties and may be used in non-fouling coatings, foams and elastomers.
