摘要： The present invention provides novel biolatex conjugate compositions and methods of production and use thereof. The novel biolatex conjugate compositions comprise a biopolymer-additive complex (prepared by co-extruding a biopolymer feedstock, at least one performance-enhancing additive, and at least one plasticizer under shear forces) reacted with a crosslinking agent under shear forces. The biolatex conjugate compositions exhibit enhanced performance properties for coated paper, paperboard, and other applications using extremely low levels of performance-enhancing additives.

摘要： A stock solution is prepared by mixing and swelling TAC as a solute in a solvent, and is fed into an extrusion machine. The extrusion machine is cooled by a cooling medium, and is provided with twin-shaft screws. The screws are a compressing type where thread pitches of a helical flight decrease toward downstream. The screws are in mesh with each other and rotated in the same direction. Through the extrusion machine, the solute is dissolved in the solvent to form a dope. The dope is further cooled in a cooler to promote the solubility of the dope. Thereafter, the dope is heated by a heater to raise the fluidity. From the obtained dope, TAC film with excellent optical properties may be formed by a solution casting method.

摘要： First and second virgin polymers, not normally miscible when combined in one or more conventional melt-processing means, are combined in a known melt-processing means having mechanical vibration, referred to as a TekFlow® “processor” in which the polymers are extensively shear-thinned, substantially disentangled and stress-fatigued. A process in which melts of each virgin polymer are separately modified, mixed and melt-processed in a conventional extruder, is also effective if the melt of one polymer, modified in a processor, is mixed with virgin melt before being modified in another processor. In each embodiment, the resulting blend is unexpectedly found to be a single phase, that is, a miscible blend.

摘要： The properties of a resinous material product are controlled in a manufacturing system by online process parameter monitoring and control. The online monitoring and control incorporates an in-situ measurement system that can monitor product in the process by use of a side stream ultrasonic device. The side stream device advantageously provides online real-time measures of the product's acoustical properties (e.g. velocity, attenuation) under conditions that are independent of process-stream conditions. The side stream device controls the product temperature, pressure, and flow rate while inside the side stream device and the velocity and attenuation are measured under these predetermined temperature, pressure, and flow rate conditions. The acoustical properties (e.g. velocity, attenuation) of the product, are used to predict the properties of the product, and provides the process control system with analysis of the acoustical properties using derived relationships between the physical properties of the product and the acoustical properties. Differences between the predicted and desired product properties are used to control process parameters. The process can be used for a variety of chemical process plants.
