Abstract:
In the disclosed method, a first fluid (36) comprising the first phase and a first precursor polymer of the coacervate in the first phase is supplied, and drops of the first fluid (36) are formed in a second fluid (40) that is to form the second phase (16). The method includes the steps of introducing a second precursor polymer of the coacervate into the second fluid (40), and creating the coacervate layer by having the first precursor polymer interact with the second precursor polymer at the interface between the first phase (14) and the second phase (16) when each drop (12) is formed or once each drop (12) has been formed.
Abstract:
The present invention relates to protective microcontainers as well as a process for preparing same. By means of the microcontainers of the invention materials enclosed therein can be protected against external influences, e.g. oxidizing or reducing agents.
Abstract:
A complex coacervate delivery system is provided which encapsulates lipophilic nutrients such as, for example, fish oils high in omega-3 fatty acids. The complex coacervate delivery system protects the lipophilic nutrient from degradation, e.g., oxidation and hydrolysis, and also reduces or eliminates the unpleasant taste and odor of the lipophilic nutrient. The complex coacervate delivery system upon ingestion is operative to substantially release the lipophilic nutrient in the lower gastrointestinal tract in a pH-controlled manner. The complex coacervate delivery system may be included in a food or beverage product having a pH value within the range of about 1.5 to about 5.0.
Abstract:
The present invention relates to novel chelate resins comprising quaternary nitrogen atoms as a functional group in structures of the general formula (I), wherein at least one of the radicals R1 to R3 stands for an optionally substituted radical of the series picolyl, methylquinoline, or methylpiperidine, m stands for a whole number from 1 to 4, and M stands for the polymer matrix, and X stands for a counterion of the series hydroxide OH-, halogenide, preferably Cl -, Br-, or sulfate SO42-, a method for the production thereof, and the use thereof, particularly the use of the new chelate resin in hydrometallurgy and galvanics.
Abstract:
The invention relates to a method for producing novel chelate resins based on cross-linked perl polymers arising from (meth)acrylic compounds having aminomethyl groups and/or aminomethyl nitrogen heterocyclic groups as functional groups possessing a high capacity for absorbing heavy metals and rapid kinetics.

Abstract:
Disclosed herein is a method of making a film, the method comprising depositing a first layer polyelectrolyte on a surface of a substrate to form a first layer; and depositing a second layer polyelectrolyte on the first layer polyelectrolyte to form a second layer. The first layer polyelectrolyte, the second layer polyelectrolyte, or both, is deposited on the substrate in the presence of a polymeric precipitant; and the first layer polyelectrolyte and the second layer polyelectrolyte have net charges of opposite polarity. Also disclosed are methods of improving bioactive molecule retention during fabrication of a polyelectrolyte multilayer film.
