摘要： The present invention involves a method of processing polyacrylonitrile into a predetermined form. The first step in this method includes preparing a solution of a room temperature solvent that will dissolve polyacrylonitrile at room temperature and, a room temperature non-solvent that will not dissolve polyacrylonitrile at room temperature. The solution is prepared with sufficient non-solvent to render the room temperature solvent inoperable such that it will not dissolve polyacrylonitrile at room temperature and such that it will be operable at temperatures above 65° C. to dissolve polyacrylonitrile therein. The second step in the present invention method involves combining polyacrylonitrile with the solution to form a mixture, in an amount of at least 20%, by weight, of polyacrylonitrile, based on the total weight of the mixture. Preferred is about 20% to about 50% by weight of the polyacrylonitrile. The third step involves processing the mixture in a hot-melt processor at temperatures in excess of 65° C. to produce a polyacrylonitrile product. An optional fourth step, which would be useful in forming medical devices and related products, involves extracting solvent from the product by liquid extraction, e.g. warm water wash.

摘要： The invention relates to a method for continuously or discontinuously producing tetrahydrofuran polymers by homopolymerization of tetrahydrofuran, alkyl-substituted tetrahydrofurans and/or alkylene oxides in the presence of carboxylic acid anhydrides or compounds containing reactive hydrogen using an optionally non-acidified or acid-activated calcined and granular natural amorphous aluminum silicate catalyst. The inventive method provides a means for substantially suppressing the formation of cyclic ethers and for obtaining a polymer with a narrow molecular weight distribution by keeping the concentration of carboxylic acid anhydrides or alkylene oxide constantly below 1 wt. % during polymerization. The catalysts have a long life span and lead to polymers that are characterized by highly uniform properties and a narrow molecular weight distribution even if a fairly impure monomer is used. The catalysts are characterized in their granulated form by a previously unknown activity and they form polymers having a very narrow molecular weight distribution and very low color index and acid number.

摘要： The present invention provides to overcome the deficiencies of the prior art, the present invention provides a method of producing a polymer. The method includes taking a product stream from a monovinyl aromatic polymerization system wherein the product stream comprises a polymerized monomer and a monomer. The product stream is introduced into an up-flow heat exchanger in a presence of an initiator, such as a peroxide, that affects a polymerization of the monomer in the up-flow heat exchanger. The initiator may include a low-temperature initiator and a high-temperature initiator where a ratio of the high-temperature initiator to the low-temperature initiator can range from about 0:600 to about 50:600.
