Cellulose-polymer composites

U.S. Pat No. 6,578,368 [51] discloses a method for cooling extruded and molded cellulosic-polymer composites, among other plastics and plastic compositions the said method uses cryogenic fluid with a temperature below about 250° F, such as liquid oxygen, liquid nitrogen, liquid neon, liquid hydrogen, and liquid helium. [Pg.83]

The effect of cellulose fiber surface treatment on the crystallization and interphase morphology of cellulose-polymer composites was studied using polarizing microscopy. Different nucleation patterns of the polypropylene matrix were observed, depending on the molecular structure of the coupling agent. [Pg.75]

An important feature of the cellulose-polymer composites is the degree of dispersion of the fibers in the matrix and the overall homogeneity of the composite structure. Prehydrolytic treatment caused a highly significant improvement in this respect. This has to do primarily with the reduction of particle size of cellulose during hydrolysis. Figure 5 illustrates that the average size of the cellulose content is considerably reduced by 2 hours of hydrolytic treatment with formic acid in gas phase. Processability, measured by melt viscosity, is dramatically improved by hydrolysis. [Pg.80]

Membrane stmcture is a function of the materials used (polymer composition, molecular weight distribution, solvent system, etc) and the mode of preparation (solution viscosity, evaporation time, humidity, etc). Commonly used polymers include cellulose acetates, polyamides, polysulfones, dynels (vinyl chloride-acrylonitrile copolymers) and poly(vinyhdene fluoride). [Pg.294]

Electric discharge methods are known [31] to be very effective for nonactive polymer substrates such as polystyrene, polyethylene, polypropylene, etc. They are successfully used for cellulose-fiber modification to decrease the melt viscosity of cellulose-polyethylene composites [32] and to improve the mechanical properties of cellulose-polypropylene composites [28]. [Pg.795]

Polymer modifications represent a valuable synthetic approach to unique polymer compositions, structure, and properties not readily available by the direct polymerization of monomers. Modified polymeric products already exist in the commercial world (modified celluloses, for example) so the approach is not new. However, it is an interesting and challenging opportunity to develop new materials for a variety of specialty applications using the "chemistry on polymers" approach. [Pg.225]
