    • Polysiloxanes terminated with one or more hydroxy functional carbamate groups are provided. The polymers may have the formula (I) wherein R 1 , R 2 , R 3 , and R 4 are independently hydrogen, C 1 - C 10 alkyl, C 1 - C 10 fluoro-substituted alkyl, cyclopentyl, cyclohexyl, benzyl, toluyl, xylyl and/or phenyl; R 5 and R 6 are linking groups; R 15 and R 16 are independently hydrogen, C 1 - C 10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluyl, xylyl or phenyl; and L 1 and L 2 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.
