Abstract: This invention is directed to polyenes derived from hydantoin acids, amines and esters. The polyene is typically a reaction product of a hydantoin amine, e.g., N,N'-bis(3-aminopropyl)-dimethylhydantoin, a diisocyanate and an unsaturated ether, e.g., trimethylolpropane diallyl ether. Upon exposure to a free radical generator, e. g., actinic radiation, in combination with a polythiol, this polyene cures to a solid, insoluble, chemically resistant, crosslinked polythioether product having excellent heat stability.

Abstract: An analytical cell assembly comprising a base with a radiation source mounted on one end, an enclosure on the other end, and a cell proper, with cell heating means, within the enclosure. The enclosure and cell have cooperative fluid flow connections whereby the cell is modular and may be simply lifted out of the enclosure. The enclosure also includes a collimating lens assembly interposed between the cell within the enclosure and the source outside the enclosure on the base. The entire assemblage of source, enclosure and cell can be moved as a unit, making it modular, or just the cell can be moved as a module leaving the enclosure and the source in place in an instrument using the invention cell assembly.

Abstract: This invention relates to a strippable coating process and a coating composition therefor comprising (1) a latex, (2) a coagulant for said latex and (3) a debonding agent consisting essentially of a substantially non-volatile additive which is adhesive to at least one of either the coated substrate or coagulated coating, more soluble in water than in the coagulated latex polymer component and having a solubility parameter at least 2(calories/cc).sup.1/2 higher than the coagulated latex polymer component.The protective coating is formed by impinging a stream of a latex and a stream of a coagulant, the two streams being oppositely charged, onto a substrate. After drying an external debonding agent is applied between the coating and the substrate and thereafter the coating is stripped from the substrate.

The thus formed amide-acid polyene either per se or after being cured in combination with a polythiol in the presence of a free radical generator will, upon heating, imidize.

Abstract: Attrition resistant and stable catalyst composition comprising crystalline aluminosilicate zeolites e.g. rare earth exchanged zeolites dispersed in an inorganic matrix containing synthetic amorphous silica-alumina and clay are prepared by a process which reduces the level of polluting ammonium salts by eliminating the use of ammonium hydroxide in the steps prior to primary filtration. During the synthesis of the amorphous inorganic matrix wherein alkali metal silicate and aluminum salt solutions are gelled and subsequently combined with zeolitic materials, the ammonia reagent is replaced by non-polluting additives such as magnesium or calcium hydroxides (or oxides) prior to a primary filtration stage without decreasing the catalytic activity of the resulting zeolite promoted hydrocarbon conversion catalysts.

Abstract: This invention is directed to thiol containing compounds having no hydrolytically sensitive groupings which are useful as polymerization transfer agents or as curing agents in curable polymer systems containing polyenes and a free radical initiator. The thiol containing compounds are formed by reacting a polyol with an allylic halide to form a poly(unsaturated ether) whose double bonds are converted to thioesters by free radical catalyzed addition of SH groups from a thiolcarboxylic acid, e.g. thioacetic acid and the like. Hydrolysis of the thioester yields the desired thiol or polythiol derivative. Alternatively the poly(unsaturated ether) is reacted with H.sub.2 S to give the desired thiol or polythiol directly in a single step. The polythiols can be chain extended by any difunctional compound that reacts with the hydroxy groups on the polythiol.
