多支链三聚氰胺聚合物
摘要：
本发明涉及一种制备多支链三聚氰胺聚合物的方法，其中使每摩尔三聚氰胺与1.5-4mol的一种或多种二胺或多胺在酸性催化剂存在下反应，所述二胺或多胺具有至少两个伯氨基。根据本发明，至多25mol％的二胺或多胺可以具有三个或更多个伯氨基，至多50mol％的二胺或多胺可以被只有一个伯氨基的胺取代。
摘要（英）：

The invention relates to a method for producing highly-branched melamine polymers, according to which melamine with 1.5 to 4 mol of one or several diamines or polyamines per mol of melamine, said diamines or polyamines having at least two primary amino groups, is reacted in the presence of an acidic catalyst. According to the invention, up to 25 mol % of the diamines or polyamines can have three or more primary amino groups and up to 50 mol % of the diamines or polyamines can be substituted by amines with only one primary amino group.
