Abstract: Release agents are provided which comprise the polymeric reaction product of a fatty diamine with a diisocyanate and, optionally, a diol. These polyurea and polycarbamate products have the following recurring formula:

WHEREIN A is an alkylene radical containing about two to six carbon atoms, B is an arylene radical containing about 6 to 16 carbon atoms, D is an aliphatic organic radical containing about two to six carbon atoms, R is an alkyl radical containing about 12 to 25 carbon atoms, R'' is hydrogen or an alkyl radical containing about one to 25 carbon atoms, a and b represent the number of recurring units and the ratio of b/a varies from 0 to 2, and c is 0, 1 or 2. Also provided are pressure sensitive adhesive tapes and release liners utilizing these novel release agents.

Abstract: A copolymeric material is provided in accordance with this invention which is the reaction product of a di (omega-thio-organo) dimethyl siloxane oligomer having terminal active hydrogen groups and a difunctional organic compound having terminal isocyanate groups. The siloxane-thiourethane copolymer provides good release per se from tacky adhesive masses or when combined with other film formers.
