Polysiloxanes terminated with one or more hydroxy functional carbamate groups are provided. The polymers may have the formula (I) wherein R1, R2, R3, and R4 are independently hydrogen, C1-C10 alkyl, C1-C10 fluoro-substituted alkyl; cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl and/or phenyl; R5 and R6 are linking groups; R15 and R16 are independently hydrogen, C1-C10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl or phenyl; and L1 and L2 are linking groups. Typically, x is such that the polymer has a molecular weight of about 1,000 to 100,000. Other polymeric materials produced by reacting with an isocyanate functional compound or a lactone and coating compositions containing such polymeric materials are also provided.
