  A process for preparing modified diene polymer rubbers having an increased impact resilience and a reduced hardness at low temperatures and useful as rubber materials for automobile tires and other industries which comprises producing an alkali metal-containing conjugated diene polymer, and reacting the alkali metal-containing polymer with a modifier selected from the group consisting of a nitro compound, a phosphoryl chloride compound of the formula: wherein R¹ to R⁴ are independently an alkyl group, and an aminosilane compound of the formula: wherein R⁵ to R⁷ are independently an alkyl group or an alkoxyl group, R⁸ and R⁹ are independently an alkyl group, and n is an integer, said alkali metal-containing diene polymer being prepared by a living anionic polymerization using an alkali metal-­based catalyst or by an addition reaction of a diene polymer having conjugated diene units and an alkali metal-based catalyst in a hydrocarbon solvent. The modified diene polymers can be incorporated with usual rubber additives to provide rubber compositions for various purposes, and the cured products show an increased impact resilience and a reduced hardness at low temperatures.

  An ion trap mobility spectrometer which employs algorithms to simultaneously detect and analyze both positive and negative plasmagrams. Selectivitly is improved by detecting the presence of peaks in both spectra and setting logic filters which require the presence or absence of certain peaks in both spectra. Selectivity is improved by looking for two peaks in the two spectra.
