Compositions are disclosed which comprise mixtures of at least one compound selected from silicone elastomers, bis-, tri- or higher polymaleimides and/or bis-, tri- or higher polyciraconimides, and at least one compound selected from p-phenylene-diamine based antiozonants, sulfur compounds capable of accelerating sulfur vulcanization of polymers capable of being crosslinked by sulfur and polysulfide polymers which when compounded into polymers curable by free radical initiators in the presence of free radical initiators permit substantially tack free surface cure of the polymers by decomposition of the free radical initiator in the presence of molecular oxygen. Compositions containing the above ingredients and at least one free radical initiator, curable compositions containing the combination and processes for making and using the compositions are also disclosed.
所公开的组合物包含至少一种选自有机硅弹性体、双马来酰亚胺、三马来酰亚胺或更高聚马来酰亚胺和/或双马来酰亚胺、三马来酰亚胺或更高聚酰胺的化合物,以及至少一种选自对苯二胺基抗佐剂的化合物的混合物、硫化合物,可加速硫磺交联聚合物的硫磺硫化;以及 聚硫聚合物,当与可通过自由基引发剂固化的聚合物复配时,在自由基引发 剂存在的情况下,通过自由基引发剂在分子氧存在下的分解,可使聚合物的 表面固化基本无粘性。此外,还公开了含有上述成分和至少一种自由基引发剂的组合物、含有该组合物的可固化组合物以及制造和使用该组合物的工艺。
