Abstract: Storage stable polyhydroxylated aromatic ether adducts of polyalkylene oxide are described. Reactive compositions are formed by combining an ether adduct with an aldehyde, optionally further adding a phenolic-aldehyde prepolymer. The reactive compositions are cured by removing water, by acidification, or both. The cured compositions sorb solvated compounds from environments containing water. The cured compositions are also useful for pre-loading with compounds that are subsequently released at a controlled rate into environments containing water.

Abstract: The present invention is directed to methods and compositions for the treatment or prevention of actinic keratosis and/or for countering the effects of skin aging and/or damage to blood vessels and fine wrinkling The present invention provides for a composition comprising aluminum fluoride or chemical compounds which releases aluminum fluoride to be used to treat or reduce the negative effects of actinic keratosis or sun-induced skin aging and associated conditions, for example, damaged blood vessels and fine wrinkling
Abstract: Cationic antimicrobial polymers have been synthesized by a bulk addition polymerization of a nucleophilic agent comprising two tertiary amines and an electrophilic agent that comprises two leaving groups and an aromatic ring between the leaving groups. The reaction solvent for the polymerization is chosen to allow precipitation of the cationic polymer at the polymerization temperature, thereby limiting molecular weight. Quaternization and polymerization occur concurrently. The cationic polymers can be highly active against Gram-negative and Gram-positive microbes, and/or fungi. The cationic polymers can also be non-hemolytic and non-cytotoxic at the effective concentration against the microbes.

Abstract: The present invention is directed to a substantially homogeneous miscible liquid adhesive composition comprising a relatively high number average molecular weight (Mn=6,000-10,000 g/mole) multi-arm star polymer having polyisobutylene chains terminated with cyanoacrylate groups (High-Ø(PIB-CA)3); 2-octyl cyanoacrylate (Oct-CA); and a low boiling point biocompatible solvent having a boiling point of not more than 37° C. When this adhesive composition contacted with living tissue and reacted with a nucleophile, such as water or an initiator, the biocompatible solvent will evaporate and the High-Ø(PIB-CA)3 and Oct-CA will co-polymerize in-situ to form a poly(2-octyl cyanoacrylate)-polyisobutylene co-network suitable for any of a number of biomedical applications, from wound closure and healing of skin tissue, to sealant for surgical cuts.

Abstract: PEHAM dendrimers of the formula: Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes. In particular, the PEHAM dendrimers may be used for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, or by improving the water-fastness of the active agent to the plant or seed. The PEHAM dendrimers may also increase the efficacy of the active agent by increasing soil penetration of the active agent to reach the plant roots or under soil parts, by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or by reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.
