    Abstract: Disclosed is a method and apparatus for the extraction of high molecular weight biopolymers from plants. Specifically, invention described herein relates to the commercial processing of plant material, including that from desert plants native to the southwestern United States and Mexico, such as the guayule plant (Parthenium argentatum), for the extraction of biopolymers, including natural rubbers. More specifically, the invention relates to laboratory to commercial scale extraction of high molecular weight biopolymers from plant materials including the chemical and mechanical processing of the plants and purification of the extracted biopolymer.

    Abstract: A method of preparing a low allergic natural rubber latex which is less likely to cause allergy, comprising adding a protease having an exopeptidase activity to a natural rubber latex and aging the natural rubber latex, thereby to decompose a protein in the latex to such a degree that the protein and a protein decomposition product, which have a number-average molecular weight of 4500 or more, are not detected; a method of preparing a deproteinized natural rubber latex which is less likely to cause allergy, comprising adding an alkali protease to a natural rubber latex, thereby to decompose a protein in the latex, adding a protease having an exopeptidase activity, thereby to further decompose the protein and a decomposition product thereof in the latex, and removing the protein and the decomposition product thereof; a low allergic natural rubber obtained by a decomposition treatment of a protein, wherein the protein and a protein decomposition product, which have a number-average molecular weight of 4500 or more, are not detected; and a deproteinized natural rubber obtained by a decomposition treatment and a removing treatment of a protein, wherein the content of the protein is 0.02% or less in terms of a nitrogen content, an absorption at 3280 cmnull1 is not recognized in an infrared absorption spectrum, and the protein and a protein decomposition product, which have a number-average molecular weight of 4500 or more, are not detected.

    Abstract: A zinc salt of a dithiocarbamic acid or of a mercaptobenzthiazole may be rendered water-dispersible by incorporation of an amine salt of a sulphated fatty acid ester. The zinc salts may be zinc N,N-dialkyldithio carbamates; salts in which the N-atom forms part of a ring; salts of N-alkyl, N-aryl dithio-carbamic acids; salts containing more than one dithiocarbamate group; or 2-mercaptobenzthiazole, optionally nuclear-substituted. The amine salts may be derived from C12 to C24 unsaturated fatty acids esterified with C1 to C8 radicals, and may be salts of C2 to C9 primary, secondary or tertiary aliphatic amines; hydroxyalkylamines; hydroxy(alkylene oxy) amines; and may be used in amounts from 0.25 to 5% by weight of the zinc salt. The composition may also contain alkali metal, ammonium or amine salts of secondary alkyl sulphuric acids derived by sulphation of C8 to C12 olefins, in amount not more than 50% of the weight of amine salt of the sulphated fatty acid ester. There may also be present 0.25 to 3% by weight of zinc salt of calcium silicate, magnesium silicate, kieselguhr, silica, alkali metal salts of carboxyalkyl cellulose, of polyacrylic acid, of partially hydrolysed polyacrylate ester or polyacrylonitrile, polyvinyl alcohol, methyl cellulose, gelatin, polyvinylpyrrolidone, bentonite. In the example, zinc 2-mercaptobenzthiazole and zinc N,N-dimethyl, -diethyl and -dibutyl dithiocarbamates are blended with the diethanolamine salt of sulphated monobutyl oleate.ALSO:A rubber stabiliser or accelerator composition comprises a zinc salt of a dithiocarbamic acid or of a mercaptobenthiazole and an amine salt of a sulphated fatty acid ester.
