An antibody includes a polyamidoamine (PAMAM) dendrimer and a first functional group. The polyamidoamine (PAMAM) dendrimer includes a plurality of branches and each of the branches has a phenylboronic acid (PBA) terminal group. The first functional group is bonded to at least one of the PBA terminal groups.

The present invention provides a polyaspartic composition comprising a reaction product of a polyamine and a Michael addition receptor reacted in the presence of a catalyst comprising a phenolic compound, with the proviso that the phenolic compound is not a phenol which is substituted with tert-butyl groups in both ortho positions to the oxygen. Suitable phenolic compounds include phenols, phenolic aldehydes, alkylphenols, benzenediols, cashew nut oil, and combinations thereof. Coatings, adhesives, sealants, composites, castings, and films comprising a polyurea composition may be made by reacting a polyisocyanate with the inventive polyaspartic composition. In particular, floor coatings made with the inventive polyaspartic composition have an elongated work time and a short walk-on time compared to current floor coatings.

A novel polymer having high glass transition temperature and an excellent balance between heat resistance, high refractive index and mechanical properties, and a composition and molded article containing the polymer are provided. The polymer according to the invention has a first structural unit represented by at least one of formulae (1-1), (1-2) and (1-3) below and a second structural unit having either a secondary amino structure or a tertiary amino structure at two or more terminals. ##STR00001##

Cross-linked polymeric resins from anilines linked together with dithiocarbamate alkyl chains. A process for producing the cross-linked polymeric resins by Mannich-type polycondensation of anilines and diaminoalkanes linked together by an aldehyde and subsequent conversion of one or more amine functionalities to dithiocarbamate moieties. In addition, a method for removing heavy metals, such as Hg(II) from aqueous solution via contacting and treatment with the cross-linked polymeric resins.

A cleaning and protectant composition and a method for using the composition on an article such as a touch screen or screen protector for a mobile device, computer, or other electronic device. The composition comprises a polymeric film former. The polymeric film former is an oxazoline homopolymer or an extended or a modified polymer based on an oxazoline homopolymer. The polymeric film former forms a retention coating to retain components within the composition for an extended period of time. The composition is also present in a kit with an application device.

Disclosed are compositions comprising a) an antimicrobial agent, which is selected from the group consisting of biocides containing halogen atoms and/or containing phenolic moieties, formic acid, chlorine dioxide, chlorine dioxide generating compounds, dialdehydes; components containing an antimicrobial metal such as antimicrobial silver, and b) a polyamine, especially a polyethylenimine. The polyamine is effective as a booster for the antimicrobial agent.

Compounds include boronate ester polythioaminals with substituents that include hydrogen, fluorine or substituted or unsubstituted alkyls. The boronate ester polythioaminals have number average molecular weight or weight average molecular weight between about 2,000 to about 160,000.

Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.

A method of forming a dendrimer hydrogel, the method comprising providing one or more amine end-functioned polyamidoamine (PAMAM) as a first reactant; providing one or more small molecule, polymer, hyperbranched molecule, or dendrimer as a second reactant, wherein the second reactant comprises one or more acrylate groups; and reacting the first reactant with the second reactant by way of conjugate addition. Compositions obtained thereby and uses thereof are also provided.
