Polymers with functional imide groups and pigment dispersions and coatings formed therefrom
A polymer having N-functional imide groups is prepared from reactants that include: (a) an ethylenically unsaturated anhydride or diacid monomer; (b) at least one co-monomer that is different from (a) having an ethylenically unsaturated group that is reactive with (a); and at least one compound reactive with the anhydride or diacid functional groups of (a) that is represented by Chemical Formula I: H.sub.2NR.sup.1. With respect to Chemical Formula I, R.sup.1 is selected from NH.sub.2 or OH. Pigment dispersions and coating compositions are also prepared with the polymers having N-functional imide groups.

Stable Star-Structured Functional Polyolefins
Stable star-structured functional polyolefins and methods of making them, the functional polyolefins comprising a polyolefin bound at any position along its chain length to at least one nucleophile-containing silane of the following formula:
##STR00001##
wherein Y is a di- or trivalent linker group selected from heteroatoms, C1 to C10 alkylenes, and other groups disclosed herein; Nu is a nucleophilic atom or unsaturation group; R5 is selected from hydrogen, and C1 to C10 alkyls, and other groups as disclosed herein; X is a divalent group selected from linear and branched alkylenes and heteroatom-alkylenes, and other groups as disclosed herein; and PO is a polyolefin having a weight average molecular weight of at least 400 g/mole; with the proviso that at least one of R1, R2, and R3 is selected from the same or different functional polyolefin moieties.

ANTIMICROBIAL SOLUTION
A solution including an antimicrobial polymer in a polar solvent and a method of producing the solution. The polymer has the structure of Formula (I). The antimicrobial solution may be coated onto a substrate and cured to provide an antimicrobial substrate in which the polymer is covalently bonded to the substrate so that it cannot leach from the substrate.

Multifunctional and multicoordinating amphiphilic polymer ligands for interfacing semiconducting, magnetic, and metallic nanocrystals with biological systems
The disclosure is directed to a set of multi-coordinating imidazole- and zwitterion-based ligands suited for surface-functionalizing quantum dots (QDs). The polymeric ligands are built using a one-step nucleophilic addition reaction between poly(isobutylene-alt-maleic anhydride) and distinct amine-containing functionalities.
