ABSTRACT:
A novel, heat curable, liquid polymer composition is disclosed which comprises a modified urethane oligomer containing terminal ethylenic unsaturation and a free radical catalyst. In a preferred embodiment, the polymer composition further includes at least one additional component selected from a reinforcing agent and a filler; the cured composition demonstrates enhanced impact properties and is particularly useful in automotive body constructions.
