    Abstract: Elastomeric interpolymers comprising at least two, or more, cyclic olefin monomers that are prepared by ring opening metathesis polymerization, and that are characterized by having no crystallinity, a glass transition temperature (Tg) of less than ?80° C., and a number average molecular weight (Mn) of at least 40 kg/mole, and functionalized products thereof. A ring opening metathesis polymerization process for producing the elastomeric interpolymers having no crystallinity. Uses of the elastomeric interpolymers in applications such as rubber compounds, tires, and the like. Cores of golf balls that are prepared by using metathesis polymerization produced elastomeric interpolymers having 0 to about 30% crystallinity.

  • Publication number: 20110293540
    Abstract: Provided herein are branched polymers synthesized from: at least one (A1) reactive monomer having a vinyl functional group, or (A2) a hybrid reactive monomer having (a) at least one vinyl functional group and (b) at least one reactive non-vinyl functional group; and at least one: (B1) branching agent having at least two N-vinyl formamide functional groups or (B2) a hybrid branching agent having (a) at least one N-vinyl formamide functional group, and (b) at least one vinyl functional group. The polymers exhibit branching behavior, which in some embodiments lends to lower viscosity, enhanced processability, and/or improved sprayability compared to a corresponding polymer of equal molecular weight synthesized without the second reactive moiety. Formulations with the invention's polymers also are presented.
