摘要： The present invention relates to an integrated process for processing and utilizing every part of the guayule plant (Parthenium argnetatum) which comprises the following steps in sequence: separating the stem and branches from the leaves of said plant with a mechanical treatment; treating the leaves to produce waxes and essential oils, and a fraction containing cellulose, hemicellulose (carbohydrates) and, to a minor extent, salts, organic compounds and lignin; extracting from the stem and branches a liquid phase, so forming a first solid woody residue, indicated with bagasse in the present text; treating said first solid woody residue to prepare sugars, resin, rubber and lignin.

摘要： Polymers useful in formulating dispersing agents for pigments are disclosed. One such polymer can be made from a glycidyl intermediate. A nucleophilic initiator can be reacted with epichlorohydrin to produce a glycidyl intermediate. This intermediate is reacted with an aralkylated phenol to give a hydroxy-functional hydrophobe. Alkoxylation of the hydrophobe gives the desired polymer. In an alternative, approach, the polymer is made by reacting the nucleophilic initiator with an aralkylated phenol glycidyl ether to give the hydroxy-functional hydrophobe, which is then alkoxylated. Pigments dispersions comprising the polymers are also disclosed. The polymers meet the growing needs of the industry with their ease of manufacture, diverse structures, and desirable performance attributes for dispersing a wide range of organic and inorganic pigments. Agricultural applications for the polymers are also disclosed.

摘要： The present invention relates to a method for obtaining rubber from rubber-containing plant material, the method comprising the steps of subjecting a composition comprising rubber-containing plant material and a fermentation culture to conditions allowing anaerobic fermentation, wherein the composition preferably has a water content of less than 95 wt. %. The fermentation preferably does not involve movement of the rubber-containing plant material (or parts thereof), and preferably the fermentation is performed in the absence of oxygen ventilation. Additionally, it is preferred that the fermentation culture is cycled through the composition by percolation. A further step of the method involves obtaining the rubber from the composition.
