标题 :Process for the synthesis of high molecular weight predominantly amorphous polymers with improved color and adhesive properties
发明人：HOLLIDAY ROBERT E; SEEGER HORST K
权利人:EASTMAN CHEM CO
摘要:The present invention relates to a continuous high molecular weight, amorphous polymer-producing process which includes a reactor design, an unreacted monomer and solvent recycling and purification system, a catalyst deactivation and polymer stabilization system, and a polymer isolation process. The present invention relates to the discovery of a continuous process for the production of polymers. The discovery relates particularly to Ziegler-Natta synthesis of amorphous polymers from alpha -olefins. In the inventive method, it was discovered that reconfiguration of process streams for the purposes of the product stabilization and catalyst deactivation led to elimination of the need for an elaborate absorption bed train to purify recycled components. Additionally, reconfiguration of process streams resulted in an improvement of process yield where recycled solvent and unreacted monomer previously caused process yield to be marginal in comparison to using entirely new feedstocks. The present invention also comprises a preferred embodiment of the synthesis of polyoctene, the separation of polyoctene from unreacted octene monomer and unreactive hydrocarbon solvent, and the deactivation of polymerization catalyst.

标题 :Synthesis of alkyl cycloalkyl dialkoxysilanes
发明人：BAND ELLIOT I; EBERHART SUZANNE T
权利人:AKZO AMERICA INC
摘要:Alkyl cycloalkyl dialkoxysilanes (e.g., methyl cyclohexyl dimethoxysilane) can be prepared by reaction of an alkyl trialkoxysilane (e.g., methyl trimethoxysilane) with a Grignard reagent containing the cycloalkyl moiety derived in the final end-product (e.g., a reagent formed by reacting cyclohexyl chloride and magnesium metal). The reaction is run in the absence of ether solvent, the Grignard reagent is preferably formed in situ by the reaction of magnesium metal and cyclohexyl halide, and agitation is used to promote the reaction. Advantageously, a catalyst, such as iodine, is used to promote the reaction.

摘要:A process for preparing long-chain branched isotactic polypropylene (LCB-PP) is provided. The process includes copolymerizing propylene with an asymmetric diene of formula I using a heterogeneous iso-specific MgCl 2 -supported Ziegler-Natta catalyst. The copolymerization results in an isotactic polypropylene-styrene (PP-St) copolymer of formula II. The process includes pelletizing the PP-co-BSt copolymer in an extruder to produce the LCB-PP. n is an integer from 1 to 4, x is an integer between 500 and 10,000, and y is an integer between 1 and 10.

摘要:A process for the production of amorphous polyolefins is disclosed. The process entails contacting the olefin monomer, in an unreactive hydrocarbon solvent, with a catalyst in a recirculated, stirred reactor thereby producing amorphous polyolefin. The reactor is capable of recirculating contents that are very viscous.
