Primary &aminer-Melvyn  L Marquis  Assistant Examiner-D.  Aylward  AttomeJ> Agent, or  Finn-Donald  F.  Haas  A crosslinkable waterborne dispersion of a hydroxy func› tional polydiene polymer composition which comprises: (a)  10 to  65  % w of a hydroxy functional polydiene polymer, (b)  0.2 to 25% w of a compatible amino resin, (c) 0.1 to 10% w  of a surfactant which is nonionic or anionic and has a  volatile cation, and ( d) the balance water. The invention also  describes a water-continuous process and an inversion pro› cesses for making such dispersions.
