摘要： Rubber, hydrocarbons, i.e., resins, and other useful by-products are extracted, recovered and isolated from shrubs such as guayule and guayule-like shrubs by a procedure wherein the entire non-defoliated shrub, after being comminuted, is processed in an aqueous and/or a non-aqueous system. An optional water treatment step can be used to remove water solubles and/or facilitate processing and achieve increased yield of desired by-products.

摘要： A process and urethane composition for making urethane prepolymers from a polyisocyanate and blends of two or more urethane intermediates. The prepolymers so produced when cured have improved physical properties such as high low strain modulus and tensile strength relative to cured polyurethanes prepared from a mixture of prepolymers prepared by reacting a polyisocyanate with the component intermediates and subsequently blending the prepolymers.

摘要： Urethane elastomers are produced by initially adding at least one incremental amount of a curing agent to a urethane prepolymer, having free polyisocyanate therein. Generally, free polyisocyanate-curing agent adducts are precipitated. Subsequently, the remaining amount of curing agent is added. Chain extension, accordingly, is favored which produces hard segment domains more evenly distributed in the polymer chain and imparts improved physical properties such as hardness, tear strength and high-low strain modulus.

摘要： scrap rubber is pyrolyzed in the substantial absence of air and treated with steam. The steam treatment can be carried out simultaneously with the pyrolysis or subsequently or it may be carried out both in part simultaneously with the pyrolysis and subsequently. Different products are obtained.

摘要： Salts generally act as reinforcing compounds in polyurethane compositions. Salts containing a free-amine function generally increase the low-strain moduli more than salts which lack such free-amine functions or are neutral. The salts are generally formed by reacting a basic nitrogen function compound such as a monoamine or a diamine with a mono or a dicarboxylic acid.

摘要： Urethane compositions generally free of phase separation patterns and flow lines are produced. One method includes the utilization of a nucleating compound which is generally added to a urethane prepolymer before any chain extension thereof. Examples of nucleating agents include urethanes, ureas and allophanates such as carboxylic acids, organic acid and anhydrides, amides, imides and the like. Another method includes adding a very small initial incremental amount of a curing agent to the prepolymer with an insoluble product being produced thereby and subsequently adding the remainder of the curing agent.
