  • Patent number: 10994174
    Abstract: A resin composition for golf balls is made of (A) polyurethane or polyurea and (B) a styrene resin material, component (B) being included in an amount of 0.5 to 50 parts by weight per 100 parts by weight of component (A). In a golf ball having a core and a cover of one or more layer encasing the core, at least one cover layer is formed of this resin composition. The resin composition is especially useful as a golf ball cover material because the ball does not fly too far and is easier to control on approach shots, yet does not sacrifice distance on shots with a driver.

  • Patent number: 10913823
    Abstract: A POSS-based non-isocyanate polyurethane modified poly(propylene carbonate) and a method of making are described. The POSS-based non-isocyanate polyurethane modified poly(propylene carbonate) includes a poly(propylene carbonate) and 1 to 20 wt % of a POSS-based non-isocyanate polyurethane. The method includes subjecting a POSS-based epoxy compound to a cycloaddition reaction with CO2 to obtain a POSS-based cyclic carbonate under an action of a catalyst, and subjecting the POSS-based cyclic carbonate to a ring-opening reaction with a monoamino compound to obtain the POSS-based non-isocyanate polyurethane. Polyurethane bonds and hydroxyl in the POSS-based non-isocyanate polyurethane serve as proton donors and forms a high-density of hydrogen bonds with carbonate units of the poly(propylene carbonate), enhancing the compatibility of the POSS-based non-isocyanate polyurethane with the poly(propylene carbonate).
