  • Publication number: 20140114034
    Abstract: The time when at least a monomer and a chain transfer agent are supplied in a reactor and the solution temperature in the reactor has reached a predetermined polymerization temperature is set as starting time (T0), and the time when a process to terminate the polymerization is started is set as ending time (T1). A polymerization initiator is supplied into the reactor between (T0) and just before [(T1)?(T0)/2] and between [(T1)?(T0)/2] and (T1). The total mass of the polymerization initiator supplied to the reactor between (T0) and (T1) is set as (IA), and the total mass of the polymerization initiator supplied between [(T0?T1)/2] and (T1) is set as (IB). The (IA) is set 50 to 100 mass % of the entire polymerization initiator. Using a production method in which 0.50<(IB)/(IA)<1.00 is satisfied, a polymer is produced at a high polymerization rate showing less variation of molecular weight and having less amount of chain transfer agent residue remaining at an end of the polymer chain.

  • Patent number: 8674004
    Abstract: A rubber composition with disperse phase particles containing poly(phenylene ether) can be formed by a method that includes melt blending an uncured rubber with a poly(phenylene ether) composition containing a poly(phenylene ether) and an oil to form an uncured rubber composition, then curing the uncured rubber composition. Before being blended with the rubber, the poly(phenylene ether) composition exhibits a glass transition temperature of about 40 to about 140° C., and during blending with the rubber, the oil component of poly(phenylene ether) composition migrates from the poly(phenylene ether) composition to the rubber, leaving a poly(phenylene ether)-containing disperse phase that gives rise to a second hysteresis peak temperature of about 160 to about 220° C. as measured by dynamic mechanical analysis of the cured rubber composition.
