High molecular weight insoluble polymers which contain functional anionic groups that are capable of undergoing exchange reactions with cations.

High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ION EXCHANGE) with either cations or anions.

High-molecular-weight insoluble polymers that contain functional cationic groups capable of undergoing exchange reactions with anions.

Separation technique in which the stationary phase consists of ion exchange resins. The resins contain loosely held small ions that easily exchange places with other small ions of like charge present in solutions washed over the resins.

Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components.

A chlorinated epoxy compound used as an industrial solvent. It is a strong skin irritant and carcinogen.

A histamine H1 antagonist used as an antiemetic, antitussive, for dermatoses and pruritus, for hypersensitivity reactions, as a hypnotic, an antiparkinson, and as an ingredient in common cold preparations. It has some undesired antimuscarinic and sedative effects.

Positively charged atoms, radicals or groups of atoms which travel to the cathode or negative pole during electrolysis.

Polymerized forms of styrene used as a biocompatible material, especially in dentistry. They are thermoplastic and are used as insulators, for injection molding and casting, as sheets, plates, rods, rigid forms and beads.

A plant species of the genus PINUS that contains isocupressic acid.

Flammable, amorphous, vegetable products of secretion or disintegration, usually formed in special cavities of plants. They are generally insoluble in water and soluble in alcohol, carbon tetrachloride, ether, or volatile oils. They are fusible and have a conchoidal fracture. They are the oxidation or polymerization products of the terpenes, and are mixtures of aromatic acids and esters. Most are soft and sticky, but harden after exposure to cold. (From Grant & Hackh's Chemical Dictionary, 5th ed & Dorland, 28th ed)

Synthetic resins, containing an inert filler, that are widely used in dentistry.

Reversible chemical reaction between a solid, often one of the ION EXCHANGE RESINS, and a fluid whereby ions may be exchanged from one substance to another. This technique is used in water purification, in research, and in industry.

The ability of a substance to be dissolved, i.e. to form a solution with another substance. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)

A colloidal, hydrated aluminum silicate that swells 12 times its dry size when added to water.
