摘要:
POLYISOPRENE HAVING THE HIGH RESISTANCE TO THERMAL AND MECHANICAL STRESSES OF NATURAL RUBBER IS PRODUCED BY INCORPORATION INTO A SOLUTION OF THE POLYISOPRENE A MIXTURE OF A DIFUNCTIONAL SECONDARY ARYLAMINE OF THE FORMULA
(4-(R2-NH-)PHENYL)-NH-R1
WHEREIN R1 AND R2 ARE ALKYL, CYCLOALKYL OR ARYL, AND AN ALIPHATIC AMINE OF THE FORMULA RN(NH)N-1(NH2)X WHEREIN X IS 1 OR 2, N IS 1-10 AND R IS ALKYL WHEN N AND X BOTH ARE 1 AND ALKYLENE WHEN N IS GREATER THAN 1.
(4-(R2-NH-)PHENYL)-NH-R1
WHEREIN R1 AND R2 ARE ALKYL, CYCLOALKYL OR ARYL, AND AN ALIPHATIC AMINE OF THE FORMULA RN(NH)N-1(NH2)X WHEREIN X IS 1 OR 2, N IS 1-10 AND R IS ALKYL WHEN N AND X BOTH ARE 1 AND ALKYLENE WHEN N IS GREATER THAN 1.
