Described are monomer compositions containing aspartic acid and other comonomers, such as monosodium aspartate, and methods for their production. The monomer compositions can be polymerized, particularly by thermal polymerization, to obtain useful and novel imide-containing polyamino acids, i.e., copolymers containing polymerized aspartate units and succinimide units. The invention is also directed to the resulting polymeric materials, their methods of production, and their uses and the derivatized polymeric materials by nucleophilic or electrophilic addition. Uses of the imide-containing polyamino acids include, for example, dispersants in detergents and cleansers, water-treatment chemicals as anti-scalants and corrosion inhibitors, personal-care additives for softening and moisturizing, and many others.
A derivatized copolymer of polymerized aspartate units and succinimide units formed by reacting an electophilic group-containing compound with at least one aspartate unit of the copolymer.
A crosslinked copolymer formed by reacting a curing agent with a derivatized copolymer containing aspartate units and succinimide units, containing a hydroxyl pendant group.
A crosslinked copolymer formed by reacting a curing agent with a derivatized copolymer containing aspartate units and succinimide units, containing an epoxy pendant group.
A crosslinked copolymer formed by addition of a free radical initiator to a derivatized copolymer containing aspartate units and succinimide units, containing a (meth)acrylate pendant functionality.
A graft copolymer formed by reacting a substantially monofunctional derivatized copolymer containing aspartate units and succinimide units with a polyfunctional polymer.
A graft copolymer formed by reacting a polyfunctional derivatized copolymer containing aspartate units and succinimide units with a substantially polyfunctional polymer.
