Methods for killing a microbial are provided that include introducing a functionalized amide polymer to a microbe, where the functionalized amide polymer includes a polymer backbone selected from polyesters and polyurethanes; an amide group with a pendant functional group, where the nitrogen atom of the amide group is part of the polymer backbone; and a net positive charge.

Thermosettable coating compositions using pendant carbamate-functional polyurethane polymers and methods of forming the thermosettable coating compositions

A thermosettable coating composition comprises a reaction product of a polyurethane polymer having at least one pendant carbamate functional group and a crosslinker reactive with the at least one pendant carbamate functional group. The polyurethane polymer is a polymerization reaction product of at least one diol having a primary carbamate functional group and at least one polyisocyanate. A method of forming a thermosettable coating composition includes polymerizing a mixture to form the polyurethane polymer, and combining the polyurethane polymer and a crosslinker reactive with the at least one pendant carbamate functional group to form the thermosettable coating composition. A coated article formed from the thermosettable coating composition is also disclosed.

Process for the production of polyurethane polyureas containing side chains and of aqueous dispersions of these
09598604 · 2017-03-21 · ·

The present invention relates to a process for the production of aqueous polyurethane-polyurea dispersions comprising the steps of: A) reacting primary and/or secondary monoamines or diamines A1) with cyclic carbonate containing one hydroxy group A2) such that the molar ratio of total primary and/or secondary amine groups to cyclic carbonate groups is in the range of 0.8 to 1.2; B) producing an NCO-containing polyurethane prepolymer by reacting B1) polyisocyanates with B2) polymeric polyols and/or polyamines having number average molecular weights of more than 400 to 8,000 g/mol, optionally B3) low molecular weight compounds having number average molecular weights of 17-400 g/mol selected from the group consisting of mono- and polyalcohols, mono- and polyamines, and aminoalcohols; optionally B4) isocyanate-reactive, ionically hydrophilizing compounds, and B5) the reaction products of A); C) dispersing the prepolymer from B) in water; and D) optionally reacting the remaining free NCO groups of the prepolymer from B) with monoamines, polyamines, hydrazine and/or hydrazides, wherein the molar ratio of the NH groups to the NCO groups is from 0 to 1.2, and step D) occurs partially or completely prior to or during the dispersion step C).
