摘要： A method for preparing aliphatic polythioether is provided. In the method, aliphatic polythioether is obtained by polymerization reaction using a sulfur-carbon compound and an oxygen-containing monomer as raw materials and using Lewis base as a catalyst, and the polymerization reaction is performed under a self-generated pressure at 80˜180° C. Based on the defects of the traditional preparation process of aliphatic polythioether, a bran-new synthetic routine is provided, in which a new process for preparing polythioether in one-pot reaction is achieved through oxygen-sulfur exchange reaction between the sulfur-carbon compound and the oxygen-containing monomer.

摘要： A rubber composition for golf balls includes (a) a base rubber, (b) a co-crosslinking agent which is an α,β-unsaturated carboxylic acid and/or a metal salt thereof, (c) a crosslinking initiator, (d) an alcohol and (e-1) an organosulfur, and the amount of component (d) is from 0.1 to 10 parts by weight per 100 parts by weight of the base rubber (a) and the organosulfur of component (e-1) is alkylphenoldisulfide polymers represented by the specific chemical formula. When the rubber composition is used in a golf ball having a core and a cover of one or more layers encasing the core, by setting the hardness difference in the core interior hardness profile to a large value while maintaining a desired core hardness, low spin properties can be manifested on golf ball shots, enabling the flight performance of the ball to be improved.

摘要： An embodiment relates to a polymerizable composition for a plastic lens. The polymerizable composition for a plastic lens according to the embodiment comprises a nonhalogenated tin-based catalyst and a diketone compound as a low-temperature reaction rate controlling agent. Accordingly, the polymerizable composition has a more stable pot life so that the polymerization rate can be appropriately controlled, thereby improving the reactivity and the workability, and that the generation of bubbles are prevented, thereby improving the transparency of the resin.
