    • Dynamic vulcanizates of an engineering thermoplastic ("plastic"), e.g. a polyamide or polyester, with acrylate rubbers having dissimilar functional groups are prepared with a metal fatty acid salt in the absence of a conventional curative, provided the rubbers are molecularly intermixed. An acrylate rubber with halogen functionality ("AcrRubHal") is thus crosslinked in a single mixing stage with an acrylate rubber having carboxyl, hydroxyl or epoxy functionality ("AcrRubX") in a "plastic". Quaternary ammonium salts and tertiary amines do not function as curatives, as one might expect. But a metal fatty acid salt, preferably a metal stearate or oleate and concentrates thereof effectively crosslink the rubbers. TPVs produced without conventional curing agents are relatively "soft", but have highly desirable low temperature physical properties and oil resistance.
    • 工程热塑性塑料(“塑料”)的动态硫化橡胶。 在没有常规固化剂的情况下,用金属脂肪酸盐制备具有不同官能团的丙烯酸酯橡胶的聚酰胺或聚酯,只要橡胶是分子混合的。 因此,具有卤素官能团的丙烯酸酯橡胶(“AcrRubHal”)在单一混合阶段与具有羧基,羟基或环氧官能团的丙烯酸酯橡胶(“AcrRubX”)在“塑料”中交联。 正如人们所期望的,季铵盐和叔胺不起作用。 但是金属脂肪酸盐,优选金属硬脂酸盐或油酸盐,其浓缩物有效地交联橡胶。 没有常规固化剂生产的TPV相对“柔软”,但具有非常理想的低温物理性能和耐油性。
