CATIONICALLY CURABLE POLYURETHANE COMPOSITIONS HAVING VINYL ETHER FUNCTIONALITY |
摘要 |
A cationically curable polyurethane composition comprises the reaction product of an organic polyisocyanate with a transvinylation polyhydric alcohol mixture containing hydroxy groups. The polyisocyanate consumes substantially all of the available hydroxy groups in the transvinylation polyhydric alcohol mixture. These compositions are particularly useful in stereolithography. A method of transvinylation utilizing ultrasonic energy is also disclosed. |
