Abstract: A method for polymerizing olefinically unsaturated carboxylic acids containing at least one activated carbon to carbon olefinic double bond and at least one carboxyl group in an organic media in which said carboxylic acid is at least partially soluble, and a nonsolvent for the polymers of said carboxylic acid, in the presence of a free radical forming catalyst and a surface active agent having an HLB value in the range of less than 10.

Abstract: An easy opening closure system comprising a container end portion having an opening therein; an exterior tape which comprises a backing and a pressure-sensitive adhesive layer and is situated circumjacent the opening; and a protective tape which comprises a barrier layer that provides a barrier to essential oils contained in beverages and an oil-resistant thermoplastic adhesive layer, the protective tape being firmly bonded to the bottom surface of the container end portion circumjacent the opening by means of the thermoplastic adhesive layer and to the exterior tape in the area of the opening by means of the pressure-sensitive adhesive layer and the thermoplastic adhesive layer.

Abstract: The invention relates to a novel purified polypeptide which is recoverable from porcine pancreas glands. The amino acid composition of the said polypeptide has been determined to be as follows:Trp (2), Lys (4), His (1), Arg (5), Asx (10), Thr (3), Ser (9), Glx (12), Pro (12), Gly (6), Ala (6), Cys 1/2 (14), Val (7), Met (2), Ile (3), Leu (1), Try (2), Phe (7), wherein the determinations are subjected to the usual error of .+-.10 percent of the indicated figures. The partial amino acid sequence comprising a total of 45 amino acids from the N-terminal, is believed to be: ##STR1## wherein pyrGlu (residue 1) stands for pyroglutamic acid. The purified polypeptide is of utility as a medicament, for example as a spasmolytic agent, as an agent for treatment of gastroduodenal ulcers and as a diagnostic aid.

Abstract: Handling problems of cadmium curing agents are minimized by adding to a nitrile rubber latex an antioxidant in the form of a soluble alkali metal salt to form a modified latex and then coagulating the modified latex with a cadmium salt to form nitrile rubber containing bound antioxidant in the form of a cadmium compound. Alternately, a concentrate containing a large proportion of the antioxidant in the form of a cadmium compound is prepared which can be subsequently added to a nitrile latex to provide the cadmate cure function.

Abstract: Particulate rubber is intimately and uniformly coated with an anti-cake(s) and pressed at mild temperatures to form friable rubber bales. The bales have a bulk density from about 1.3 to about two times that of the original particulate rubber and are capable of being handled as a slab and of supporting a direct load, yet break down under shear to form particles substantially similar in size and distribution to that of the original particulate rubber.
