摘要： Copolymers of polyaspartic acid which are suitable for the inhibition of scale deposition were obtained by reacting maleic acid, an additional polycarboxylic acid and ammonia in a stoichiometric excess, at 120.degree.-350.degree. C., preferably 180.degree.-300.degree. C., to provide copolymers of polysuccinimide. In a second embodiment, a polyamine was added to the reaction mix. These intermediate polysuccinimide copolymers could then be converted to the salts of copolymers of polyaspartic acid by hydrolysis with a hydroxide. Such copolymers are useful in preventing deposition of scale from water and find applications in treating water. Other applications include scale prevention additives for detergents. In addition, such copolymers inhibit dental tartar and plaque formation.

摘要： Disclosed are methods of producing super-absorbing polymeric networks of polyaspartates from crosslinked polysuccinimide. In one preferred aspect, polysuccinimide is first reacted with an organic crosslinking agent, preferably an organic base containing at least two primary amine groups, to form a gelled crosslinked polysuccinimide. The gelled crosslinked polysuccinimide is then base hydrolyzed to a gelled polymeric network of polyaspartate and deswollen with at least one liquid alcohol to a polymeric network of polyaspartate which demonstrates super-absorbing capability in water and in electrolyte solution. Super-absorbing polymeric networks of polyaspartates can also be produced in a single reaction vessel by sequentially crosslinking a polysuccinimide with an organic crosslinking agent in an aqueous reaction medium, optionally containing a mineral acid, and then hydrolyzing the crosslinked polysuccinimide to produce a polymeric network of polyaspartate.

摘要： Thermal polymerization of a salt of aspartic acid affords polyaspartate directly without hydrolyzing polysuccinimide. Copolymerization of a salt of aspartic acid with aspartic acid itself affords a copolymer of succinimide and aspartate which may be readily derivatized to produce a sulfonated, phosphonated or hydrophobized polymer.
