Usage

General Description

DI(ETHYLENE GLYCOL) ETHYL ETHER METHACRYLATE, also known as DEGEMA, is a chemical compound that is commonly used as a reactive diluent in the production of adhesives, coatings, and resins. It is a clear liquid with a mild, pleasant odor and is highly flammable. DEGEMA is also utilized in the manufacturing of acrylic polymers and as a co-monomer in the production of thermosetting plastics. This chemical is considered to have moderate toxicity and can cause skin and eye irritation upon contact. However, it is not expected to be harmful if used in accordance with proper handling and safety procedures.

Cytosol-specific fluorogenic reactions for visualizing intracellular disintegration of responsive polymeric nanocarriers and triggered drug release

Supramolecular aggregates of stimuli-responsive block copolymers are increasingly utilized as drug nanocarriers. Although in situ tracking their triggered disintegration and drug release processes at the cellular level is highly desirable, it remains a considerable challenge. We report the fabrication of double hydrophilic block copolymers covalently conjugated with ?±,?2-unsaturated ketone-caged coumarin functionalities in the thermoresponsive block. Upon thermo-induced micellization and cellular uptake, Michael addition reaction of unsaturated ketone moieties with thiol compounds (GSH and Cys) in the reductive subcellular compartments leads to micelle-to-unimer transition. This is accompanied by concomitant fluorescence emission turn-on and triggered drug release, allowing for the process visualization.

Unique associative properties of copolymers of sodium acrylate and oligo(ethylene oxide) alkyl ether methacrylates in water

A series of random copolymers of sodium acrylate and oligo(ethylene oxide) alkyl ether methacrylates (CnEmMA) with different lengths of ethylene oxide (EO) and alkyl groups were prepared by free-radical copolymerization at varying copolymer compositions. The lengths of the EO units (the number of EO units) (m) and the numbers of carbon atoms in the alkyl groups (n) ranged fro'm 0 to 8.7 and 1 to 6, respectively. The copolymers with n = 1 and m = 1-8.7 exhibited a marked increase in solution viscosity at polymer concentrations (Cp) higher than their overlap concentrations (C*) when the CnEmMA contents (x) in the copolymers were in a certain limited range. Namely, there was an optimum x value that yielded the highest viscosity as a consequence of the competition between inter- and intrapolymer associations; the maximum viscosities occurred around x ≈ 25, 15, 10, 7, and 3 mol % for m = 1, 2, 3, 4.2, and 8.7, respectively. The maximum viscosity decreased significantly as n was increased on going from 1 to 6, and for the copolymers with n = 6, no increase in the viscosity occurred, a trend opposite to what is expected to interpolymer hydrophobic associations. When Cp > C*, steady-shear viscosity depended on the nature of countercations; the viscosities were found to be higher in the order Li + > Na+ ? NH4+, whereas reduced viscosity in dilute regime (Cp C*) was independent of the species of the cations. Rheological properties were found to be typical of transient networks formed through very weak interpolymer associations. Thus, the large increase in solution viscosity was explained by simultaneous interactions of countercations with EO units via coordination and with the polyanion via counterion condensation.
