    摘要: NOVEL COMPOUNDS HAVING THE STRUCTURE

    R1-N(-R2)-C(=S)-S-CH2-(S)X-CH2-S-C(=S)-N(-R3)-R4

    WHERE R1 AND R2 ARE ALKYL OR ARYL, R2 AND R4 ARE ALKYL WITH THE UNDERSTANDING THAT R1 AND R2 AND R3 AND R4 MAY FROM A RING, AND WHERE X IS AN INTEGER OF FROM 2 TO 6. THESE NEW COMPOSITIONS ARE USEFUL AS ACCELERATORS FOR THE SULFUR VULCANIZATION OF UNSATURATED ELASTOMERS AND MAY BE USED AS VULCANIZING AGENTS.

    摘要: A PROCESS FOR SHORT-STOPPING POLYMERIZATIONS, PARTICULARLY POLYMERIZATION PROCESSES FOR MAKING SYNTHETIC RUBBER LATICES SUCH AS BUTADIENE-STYRENE COPOLYMERS, WHERE THE SHORT-STOPPING AGENT IS A HYDROQUINONE TERTIARY AMINE OXIDE OF THE STRUCTURE

    (R)M,(R3-R2-N(=O)-CH2)N-HYDROQUINONE

    WHERE R IS AN ALKYL RADICAL, CHLORINE, BROMINE, NITRO OR A -(CH2NR2R3) GROUP; M IS 0 OR 1; R2 AND R2 ARE ALKYL RADICALS, B-HYDROXYALKYL RADICALS, OR OXYDIETHYLENE WHEN TAKEN TOGETHER; AND N IS 1 OR 2.
