A device and method used to help reduce aches and pains to joints, muscles, and other body parts; helps to relieve swelling; provide support to joints and muscles. Comprising of a plurality of ridgesaffixed to a flexible thermal sheet. Said ridgesproduce an acupressure-like massage effect and the flexible thermal sheetabsorbs and reradiates heat between the device and skin producing a self-heating effect. The device can be sized for a particular application. A user places the device against his or her body part and device is held in place by a method of user's choice.

Copolymers of styrene and sodium styrene sulfonate can be combined with a plasticizer to make a non-PVC plastisol sealant for containers.

Styrene sodium styrene sulfonate copolymer for plastisol sealant

A tin catalyst constituting an organotin compound modified with an amine is used to catalyze the hydrolysis of latent amine curing agents in amine-curable polymeric compositions. The tin catalyst is formed from the reaction product of a stannous alkanoate and an amine, optionally in the form of an adduct with water. A preferred catalyst is the reaction product of stannous octoate and ethylenediamine.

Tin catalysts for hydrolysis of latent amine curing agents

An adhesive composition for adhering two substrates includes a mixture of acrylate and epoxy with a tri- or tetrafunctional ketimine as a curing agent. The adhesive composition provides a two-stage cure in which, in a first stage, the adhesive is moisture cured at ambient temperature to provide green strength. In a second stage, the adhesive is post-cured at elevated temperatures to provide a high strength bond. The ketimine is formed form the reaction of diisopropyl ketone and an amine.

This invention relates to a screen printable, opaque legend ink composition curable on exposure to radiation, e.g., UV radiation in the presence of a photoinitiator or high energy ionizing radiation comprising

Screen printable, UV curable opaque legend ink composition

This invention relates to a process for preparing thiols and polythiols by the addition of a thiolcarboxylic acid, e.g., thiolacetic acid, to ethylenically unsaturated compounds in the presence of an initiator comprising a pinacol of the general formula: ##STR1## wherein R.sub.1 and R.sub.3 are members independently selected from the group consisting of substituted and unsubstituted aromatic radicals, R.sub.2 and R.sub.4 are members independently selected from the group consisting of substituted and unsubstituted aliphatic and aromatic radicals and X and Y are members independently selected from the group consisting of hydroxyl, alkoxy and aryloxy to obtain a thiol ester which is thereafter hydrolyzed to yield the corresponding thiol.

The invention is directed to alkali-resistant, radiation curable compositions comprising

Alkali-resistant radiation curable ene-thiol compositions

This invention relates to a solid curable composition formed by adding finely divided urea in amounts ranging from 10 to 70 weight percent of the composition to liquid polyene/polythiol curable systems wherein the combined polyene and polythiol contain at least 20 percent by weight of oxyethylene units. The thus formed solid compositions are readily cured by radiation, e.g., high energy ionizing radiation or U. V. radiation in the presence of a photocuring rate accelerator.
