FIELD: chemistry.
SUBSTANCE: invention relates to silicon-containing azodicarboxamides which can be used in rubber mixtures. Disclosed are silicon-containing azodicarboxamides of formula [(C13H27(-O-CH2-CH2)5-O-)1,5(EtO)1,5Si-(CH2)3-NH-C(=O)-N=]2, [(C13H27(-O-CH2-CH2)5-O-)1,3(EtO)1,7Si-(CH2)3-NH-C(=O)-N=]2, [(C13H27(-O-CH2-CH2)5-O-)1,4(EtO)1,6Si-(CH2)3-NH-C(=O)-N=]2, [(C13H27(-O-CH2-CH2)5-O-)1,7(EtO)1,3Si-(CH2)3-NH-C(=O)-N=]2 or [(C13H27(-O-CH2-CH2)5-O-)1,6(EtO)1,4Si-(CH2)3-NH-C(=O)-N=]2, as well as a method of preparing rubber mixtures using said rubber mixtures, corresponding rubber mixtures and use thereof.
EFFECT: use of the disclosed silicon-containing azodicarboxamides in filled rubber mixtures enables to improve the performance of rubber mixtures, such as tensile modulus at elongation by 300 %, torque difference and tear resistance.
