Novel ionene polymers are formed by the mannich reaction of an aromatic molecule having an electron withdrawing group with a lower aliphatic aldehyde and a lower aliphatic secondary amine followed by polymerizing the manniched derivative by the use of chain extenders from the group of di-functional condensation monomers consisting of alkyl dihalides, epihalohydrins and 1,4-dihalobutene-2. Additionally, the polymers may be prepared by substituting some or all of the secondary amines above with a primary amine, and quaternizing the resultant polymers formed. The product of this invention have present utility as polymers useful for water clarification and as emulsion breakers for water-in-oil or oil-in-water emulsions.
新型离子烯聚合物是通过芳香分子与一个带有电子吸引基团的低级脂肪醛和一个低级脂肪二级胺进行曼尼希反应形成的,随后通过使用来自双官能基缩聚单体组的链延伸剂对曼尼希衍生物进行聚合。这些组分包括烷基二卤代物、环氧卤代醇和1,4-二卤基丁烯-2。此外,这些聚合物可以通过将上述某些或全部的二级胺替换为一级胺,并季铵化所形成的聚合物来制备。该发明的产品可用作用于水澄清和作为水包油或油包水乳化剂破乳剂的聚合物。
