摘要： A resin composition for golf balls includes specific amounts of (A) polyurethane or polyurea and (B) an oxazoline group-containing acrylic polymer or an oxazoline group-containing styrene polymer. A golf ball having a core encased by a cover of one or more layers, wherein at least one cover layer is formed of this resin composition, exhibits a good adhesion between adjoining layers, enabling the ball to achieve a high scuff resistance without lowering the initial velocity of the ball.

摘要： Provided is a crude oil dispersion stabilizer containing a vinyl alcohol-based polymer, wherein a degree of saponification of the vinyl alcohol-based polymer is greater than 70 mol % and 82 mol % or less, and the total content of carboxyl groups and lactone rings is 0.02 to 1 mol % relative to all structural units of the vinyl alcohol-based polymer. According to this, there is provided a crude oil dispersion stabilizer capable of dispersing or emulsifying a highly viscous crude oil, thereby reducing the viscosity and allowing the resulting crude oil dispersion liquid or emulsion to be present stably for a long time.

摘要： The present invention relates to a commercial reaction process for the selective oligomerization reaction of ethylene, and a method for efficiently removing reaction heat to be generated in a reaction and regulating the temperature of the reactor and, more specifically, to an oligomerization reaction process of ethylene by circulating a liquid mixture in the reactor, separating unreacted ethylene from this circulation flow by an apparatus for separating unreacted ethylene from the circulation flow, and then cooling the remaining mixture and reintroducing it to the reactor, thereby removing the reaction heat in the reactor and allowing temperature control.

摘要： A process for making preseed particles comprising, consisting of, or consisting essentially of the steps of: mixing initial seed latex particles; a monomer mixture comprising at least one monomer and at least one copolymerizable surfactant, at least one initiator and a chain transfer agent, is disclosed. The preseed particles, a monomer mixture comprising at least one monomer and at least one copolymerizable surfactant, and at least one initiator can then be mixed to form oligomer seed particles.

摘要： Disclosed herein are dual catalyst compositions containing an unbridged metallocene compound, a bridged metallocene compound, a chemically-treated solid oxide, and an optional co-catalyst. These catalyst compositions can be used for the oligomerization of propylene to produce an oligomer product. For example, a heavy propylene oligomer can be recovered from the oligomer product, and the heavy propylene oligomer can be characterized by a high flash point and viscosity index, and a low pour point.
