resin

 [rez´in]
1. a solid or semisolid organic substance exuded by plants or by insects feeding on plants, or produced synthetically; they are insoluble in water but mostly soluble in alcohol or ether. adj., adj res´inous.
2. a compound made by condensation or polymerization of low-molecular-weight organic compounds.
acrylic r's products of the polymerization of acrylic or methacrylic acid or their derivatives, used in fabrication of medical prostheses and dental restorations and appliances.
anion exchange resin see ion-exchange resin.
cation exchange resin see ion-exchange resin.
cholestyramine resin a synthetic, strongly basic anion exchange resin in the chloride form which chelates bile salts in the intestine, thus preventing their reabsorption; used as an adjunctive therapy to diet in management of certain hypercholesterolemias and in the symptomatic relief of pruritus associated with bile stasis.
composite resin a synthetic resin, usually acrylic based, to which a high percentage of ceramic reinforcing filler has been added, such as particles of glass or silica coated with a coupling agent to bind them to the matrix; used chiefly in dental restorations. Called also composite.
epoxy resin a tough, chemically resistant, adhesive, flexible, dimensionally stable resin of epoxy polymers; used as denture base material.
ion exchange resin a high-molecular-weight insoluble polymer of simple organic compounds capable of exchanging its attached ions for other ions in the surrounding medium; classified as (a)cation or anion exchange resins, depending on which ions the resin exchanges; and (b) carboxylic, sulfonic, and so on depending on the nature of the active groups.
podophyllum resin a mixture of resins from podophyllum, used as a topical caustic in treatment of laryngeal papillomas, condylomata acuminata, and other epitheliomas.

res·in

(rez'in, rŏz'),
1. An amorphous, brittle substance consisting of the hardened secretion of various plants, probably derived from a volatile oil and similar to a stearoptene.
2. Synonym(s): rosin
3. A precipitate formed by the addition of water to certain tinctures.
4. A broad term used to indicate organic substances (often polymeric) insoluble in water; the monomer's subunits are named according to their chemical composition, physical structure, and means of activation or curing, for example, acrylic resin, autopolymer resin.

resin

  1. any of a mixed group of compounds, including resin ACIDS, ESTERS and TERPENES that are found notably in plants, particularly trees and shrubs. Resins are often exuded from wounds, following injury or the infection of plants by, for example, FUNGI.
  2. a polymerized support used in, for example, CHROMATOGRAPHY.

Anion exchange resin showed better correlation with sodium bicarbonate, good correlation with ammonium acetate buffer as well as with sodium acetate buffer and non significant correlation with other two extractants.
Batch decolorization experiments were conducted with the crude filtered vancomycin broth by adding 1g (based on dry weight) of various anion exchange resins to 20mL of broth, and shaking the contents for four hours.
The highest levels of phosphorus in the vineyard soil were found mainly in labile fractions extracted with anion exchange resin ([Pi.sub.RTA]) and NaHC[O.sub.3] ([Pi.sub.bic] and [Po.sub.bic]), which can increase high nutrient availability to plants, but also indicates the potentiation of solution transfer from soil to surface run-off or percolated through the soil profile, which represents greater potential for contamination of surface and subsurface waters.

Solvent extraction has been used for the recovery of metals by means of hydrometal-lurgical process but this method is not used commercially for the purification and concentration of gold (Caravaca et al., 1996).Gold can be absorbed and eluted effectively using either strong or weak base anion exchange resins. Loading strong base resins with gold cyanide is an ion exchange mechanism involving the exchange of resin anions.
