Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
114 words
A composition capable of being cured to an elastomer by irradiation comprising an organopolysiloxane having an average of at least one nitrogen containing group per molecule linked to a silicon atom through an Si--N or Si--O--N linkage and a photo-induced free radical generating compound in an amount of from about 0.01 to 20 percent by weight based on the weight of the siloxane, said nitrogen containing organopolysiloxane is obtained from the reaction of an organopolysiloxane having at least two hydroxyl groups per molecule with an organosilicon compound having an average of more than one nitrogen containing reactive group per molecule selected from the group consisting of an amine, aminoxy, amide, oxime and mixtures thereof.
Claim 2
Dependent Claim
