  • Patent number: 8487063
    Abstract: Methods for making polyurea polymer compositions are provided. The methods involve preparing an amine-terminated first prepolymer by reacting isocyanate compound A with a stoichiometric excess of polyamine. The first prepolymer is reacted with a stoichiometric excess of isocyanate compound B to form an isocyanate-terminated second prepolymer. The second prepolymer is reacted with a chain extender. The polymer compositions can be used in different products and are particularly suitable for making golf balls. For example, the polymer compositions can be used to make golf ball covers.

  • Publication number: 20130131301
    Abstract: Disclosed is a method for making waterborne polyurethane with a reactive functional group. The method includes the step of introducing a short-chain diol monomer with a reactive functional group into waterborne polyurethane polymer by pre-polymerization to provide a polyurethane pre-polymer with the reactive functional group connected to a side chain and the step of reacting the pre-polymer with hydrophilic diamine for chain extension and inter-crosslink to provide waterborne polyurethane with different crosslink degree.
