    摘要: In some variations, the invention provides a method and additive for improving melt strength and processing stability in polymer blow molding or blownfilm extrusion, comprising: providing a polymer or a combination of polymers; forming a melt phase of the polymer(s); and introducing nanocellulose to the melt phase, wherein the introduction of the nanocellulose increases the melt strength of the melt phase. The nanocellulose may include hydrophobic or hydrophilic nanocellulose. The nanocellulose may include lignin-coated cellulose nanocrystals and/or lignin-coated cellulose nanofibrils. The nanocellulose may be present in the melt phase at a concentration of about 0.01 wt% to about 10 wt%, for example. The nanocellulose is preferably obtained from an AVAP® lignocellulosic biomass fractionation process.

    摘要: The present disclosure relates to a process for recovering a polyester component and products of a non-polyester component from an article containing a polyester blend. The polyester blend consists of a polyester component and a non-polyester component. Particularly, the polyester component of the present disclosure is polyethylene terephthalate and the non-polyester component is at least one selected from the group consisting of cotton and viscose. The process of the present disclosure includes hydrolyzing the article using at least one hydrolyzing agent having pH ranging from 7 to 14 to obtain a first mixture containing the polyester component, the non-polyester component, optionally, products of the non-polyester component and the hydrolyzing agent. This is followed by incubating the first mixture using at least one enzyme selected from the group consisting of cellulase and pectinase to further convert the non-polyester component into products of the non-polyester component thereby releasing the polyester component.

    摘要: The present invention provides a method for manufacturing a rubber composition, the method making it possible to obtain a rubber composition having exceptional reinforcing properties by improving the dispersivity of fibers in a rubber component when a rubber is compounded with the fibers. The present invention also provides a rubber composition obtained using the method, a vulcanized rubber, and a tire. The present invention is a method for manufacturing a rubber composition containing short fibers. The method includes a liquid-dispersion preparation step for preparing a short-fiber liquid dispersion by adding short fibers to a liquid, a mixed liquid dispersion preparation step for admixing at least one dispersant selected from the group consisting of carbon black and an inorganic compound into a short-fiber liquid dispersion to prepare a mixed liquid dispersion, a mixing step for mixing the mixed liquid dispersion and a latex rubber to prepare a rubber/short-fiber liquid mixture, and a drying step for drying the rubber/short-fiber liquid mixture to obtain a rubber composition.

    摘要: The invention describes solutions containing cellulose and a method of dissolving lignocellulosic materials. In the method, the lignocellulosic material is contacted with a conjugate acid, formed by a strong organic base and a weaker acid, under conditions which are conducive to at least a partial dissolution of the cellulosic components of the lignocellulosic material. It has been found that it is possible to recover at least a portion of the dissolved part of the lignocellulosic material by at least partial dissociation of the conjugate acid. Furthermore it is possible to recover at least a portion of the dissociated organic base and the acid, to form a conjugate acid of the recovered base and acid, and to recycle it for use in the first steps of the method.
