Abstract: A multiblock, cationic-functionalized norbornene copolymer is formed by a process including performing a vinyl addition polymerization in the presence of a metal catalyst of a first norbornene monomer substituted with a first alkyl group and a second norbornene monomer substituted with a second alkyl group by adding a predetermined amount of the first norbornene monomer and a predetermined amount of the second norbornene monomer sequentially to the reaction to form blocks of an intermediate norbornene multiblock copolymer. The second alkyl group includes a substituent which undergoes a reaction with a precursor for a cationic group having a volume less than 0.25 cm3/mol. The process further includes reacting the precursor for the cationic group with the intermediate norbornene multiblock copolymer to form the multiblock, cationic-functionalized norborene copolymer.

Abstract: A statistical, cationic-functionalized norbornene copolymer is formed by a process including performing a vinyl addition polymerization in the presence of a metal catalyst of a first norbornene monomer substituted with a first alkyl group and at least a second norbornene monomer substituted with a second alkyl group, to form an intermediate norbornene copolymer. The second alkyl group includes a substituent which undergoes a substitution reaction with a precursor of a cationic group. The process further includes adding the precursor for the cationic group to the intermediate norbornene copolymer to form the cationic functionalized norbornene copolymer. The cationic group has a volume of 0.25 cm3/mol or greater (for example, a phosphonium group or an imidazolium group).

Abstract: Provided is an elastic infill for artificial turf. The elastic infill is produced by pelletization of an elastomer composition comprising a silane coupling agent and a mixture of an olefin copolymer-containing base resin and an inorganic filler. The silane coupling agent is present in admixture with the mixture. Alternatively, the silane coupling agent may be grafted onto the olefin copolymer to allow cross-linking of the olefin copolymer in the presence of water.
