Abstract
Diblock copolymers are obtained by addition of monofunctional telomers to aromatic diisocyanates [telomers of butyl acrylate or methyl metha crylate with mercaptoethanol]. These copolymers were synthesized in tw o steps: preparation of a prepolymer from a monofunctional telomer and a diisocyanate, then, condensation of the prepolymer isocyanate funct ion with a second telomer. Acrylic diblock copolymers with different c hain lengths have been prepared according to this procedure.
