摘要： A block copolymer of polyalkalene oxide and a polydiene is made by the lithium catalyzed anionic polymerization of a diene followed by polymerization of an alkalene oxide using a double metal cyanide catalyst. The dispersant can be used in forming a crude oil methanol dispersion for transport through unheated pipelines from the North Slope oil fields to Prudhoe Bay.

摘要： Divinyl benzene and/or diisopropenyl benzene in hydrocarbon solvent is added over a period of time at low temperature to a hydrocarbon solvent containing a C.sub.2-20 normal, secondary or tertiary alkyl or cycloalkyl lithium compound and a tertiary alkylamine having 2-4 carbon atoms prepared at low temperature to provide an initiator having an average of from 4 to 9 C-Li sites and a VPO Mn of from about 750 to 4,000. These initiators a re useful in polymerizing dienes and vinyl monomers to provide star polymers having an average of from about 4 to 9 arms or branches. These star polymers among other things are useful low profile or low shrink additives for FRPs, e.g., glass fiber reinforced plastics.

摘要： A laminated product such as a tire is cast from chemically extending liquids which form a laminated solid in a mold. The mold cavity is closed in preparation for use except for casting fluid inlet ports and exhaust vents. The mold cavity defines the shape of the product to be cast. Two or more chemically extendable liquids are injected into the mold without mixing through the inlet ports. Each liquid is injected through a different port. After injection, the liquids are arranged in alternate circumferential segments within the annular space. At least one of the inner and outer surfaces which define the mold cavity is then rotated about the common axis to impart a spiral configuration to each of the injcted liquids. The liquids are then allowed to chemically extend to solids and form a laminated product such as a tire. The products, when they comprise alternate layers of high and low elastic modulus materials, have better resistance to flex cracking than non-layered materials of similar composition having similar average stiffness.
