    • A continuous process for the aminolysis of polymers produced from ethylenically unsaturated structural units comprising contacting, in a reaction vessel,(a) a molten polymer containing structural units produced from alpha-olefins having from 2 to 8 carbons atoms, and esters of of .alpha.,.beta.-ethylenically-unsaturated carboxylic acids in a reaction vessel; and(b) a liquid phase comprising an amine-containing compound, e.g., an alkylamine having an alkyl group containing 1-30 carbon atoms, ammonia, or derivatives thereof, in the presence of(c) a catalytically effective amount of a catalyst, which is preferably a metal-containing solution, for a period of time effective to produce a polymer containing acrylamide structural units, wherein the period of time is less than about 1 hour.This process is performed continuously in a reaction vessel, preferably in at least one reactive extruder, under conditions effective to provide an ethylene co-polymer containing acrylamide structural units.
    • 用于由烯属不饱和结构单元生产的聚合物的氨解的连续方法包括在反应容器中使(a)含有由具有2至8个碳原子的α-烯烃制成的结构单元的熔融聚合物和α, β-烯属不饱和羧酸在反应容器中; 和(b)在(c)催化有效量的催化剂的存在下,包含含胺化合物,例如具有含有1-30个碳原子的烷基的烷基胺,氨或其衍生物的液相, 其优选为含金属溶液,持续一段时间有效地制备含有丙烯酰胺结构单元的聚合物,其中所述时间段小于约1小时。 在有效提供含有丙烯酰胺结构单元的乙烯共聚物的条件下,在反应容器中优选在至少一个反应性挤出机中连续进行该方法。
