Abstract: A process for decontaminating water, comprising contacting the water with iodine, contacting the solution with a nylon polymer selected from the group consisting of nylon-6, nylon-4,6 and nylon-6,6, and then separating the so-formed iodophor from the solution.

Abstract: A class of water insoluble iodophors comprising complexes of iodine with various nylons such as nylon-4,6, nylon-6, nylon-6,6 or other polyamides is disclosed. These nylons complexed with iodine can be made in various forms such as powders, pellets, molded objects, granules, films, monofilaments, and either non-woven or woven fabrics. These nylon based iodophors and other water insoluble iodophors herein disclosed can find product applications in the fields of air treatment, water treatment, public hygiene and medicine.

Abstract: The present invention provides methods and reagents for assessing lipoprotein metabolism. The methods provided are applicable for use on multiple samples in a clinical laboratory, thus obviating the need for sophisticated instrumentation, such as flow cytometry. Selected cell types in a test sample are uniformly labelled with a detectable reporter substance, so that they may later be enumerated. Pre-determined lipoprotein receptors associated with the cells of interest are labelled with a receptor-selective marker, thereby to determine the number of lipoprotein receptors per cell in the test sample. Selected cells of interest are conveniently separated from the test sample by binding thereto a specific binding substance attached to a solid support. The specific binding substance binds specifically with a characteristic determinant of the cell subset of interest. The remainder of the test sample may be washed away or discarded.

Abstract: A process for the polymerization of caprolactam to nylon-6 polymer, comprising the use of a polymerization accelerator having the structural formula ##STR1## wherein R.sup.1, R.sub.2, R.sub.3 and R.sub.4 are alkyl, aryl and aralkyl radicals and mixtures thereof, and X is a halogen ion other than iodide and the temperature of said polymerization process is carried out at between about room temperature and about 115.degree.
