    Abstract: This invention relates to water-soluble/dispersible reactive imido and polyimido compounds, wherein the polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compounds comprise a water-solubilizing/dispersing moiety that provides water-solubility and/or water-dispersibility to the polyimido compound and preferably is derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates. The present invention also pertains to a proteinaceous substrate to which the imido or polyimido compound has been covalently bonded and to a method for treating a proteinaceous substrate with the imido or polyimido compound.

    Abstract: This invention relates to a two-part system useful for treating proteinaceous substrates. The two-part system has a first part comprising a water-soluble/dispersible reactive polyimido compound and a second part comprising a nucleophilic catalytic agent. The polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compound may also comprise a functionalizing moiety that provides functionality to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates; and a water-solubilizing/dispersing moiety that provides water-solubility and/or water-dispersibility to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates. The nucleophilic catalytic agent serves to catalyze nuclephilic substitution of the polyimido compound by the proteinaceous substrate. The invention also pertains to a method for treating a proteinaceous substrate with the two-part system and to a composition comprising a mixture of the polyimido compound and the nucleophilic catalytic agent.

    Abstract: A seed coating composition for low temperature applications, said seed coating composition comprising at least one polymer having a Tg of −60° C. to 20° C., provided that the Tg of the polymer is less than or equal to the seed surface temperature at the time of application. The seed coating compositions of the invention provide a matrix which entraps active ingredients and improves seedling survival by maintaining the active ingredient on the surface of the seed for a period of time. The seed coating also increases the safety of using an active ingredient by reducing operator exposure and environmental release. In addition, the seed coating composition is resistant to cracking and flaking even when the seed coating composition is applied at a temperature of less than 20° C. Moreover, the seed coating composition improves the uniformity of seed size and shape which is advantageous to mechanical planting techniques.
