UV curable, liquid, oligomeric compositions are prepared from the reaction product of a Michael addition oligomer and an isocyanate capped polybutadiene. The UV curable, liquid, oligomeric compositions can be cured in the presence of fragrances to form articles that are characterized by a controlled release of the fragrance over time.
