摘要:
The invention relates to a method for the detection and/or measurement of a phenol comprising: (a) contacting the sample to be tested with a polymer imprinted with the phenol or an analogue thereof; and (b) measuring binding of the phenol to the polymer. The polymer may be prepared by polymerising a polymerisable monomer, to which a phenol is covalently bound by a hydrolysable linker, and subsequently removing the phenol by hydrolysis. Propofol is a preferred phenol for use in the invention.

摘要:
Organic glasses and surface coatings are prepared, with short hardening cycles, by submitting to the action of U.V. light a liquid polymerizable composition containing at least one di-(allyl carbonate) or poly-(allyl carbonate) of a diol or polyol, a photoinitiator and a vinyl ester monomer and/or an organic peroxide. The composition can additionally contain small amounts of an organic compound selected from among those compounds which are used in the art in order to stabilize the organic polymers to the degrading action of U.V. light. The composition is preferably heated before being treated with U.V. iight.

摘要:
Polyol(allyl carbonate), e.g., diethylene glycol bis (allyl carbonate), are polymerized in solution, i.e., in an organic solvent, until from 15 to 50 percent of the allylic carbon-carbon linkages are consumed. The solvent is then removed yielding a product that is gel-free, syrupy viscous liquid of unpolymerized monomer and polymer. This liquid polymer can be polymerized to a hard, transparent material with less shrinkage. Also described is the addition of mono- or polyfunctional acrylates to the liquid polymer to produce a polymerizable mixture that can be cured quickly with the addition of a free-radical initiator.
