摘要： A cellulose ester film which can be melt cast is manufactured by esterfying cellulose to form a cellulose acetate or cellulose acetate propionate having degrees of substitution of DSac=1.9 to 2.6, DSpr=0 to 0.9 and DS.sub.OH =0 to 0.55 and melt compounding the resulting polymer with a non-volatile phosphoric acid ester. A film is formed by melt extruding the compounded polymer onto a cooling surface to form a solid film. The film is then biaxially oriented at 130.degree. to 200.degree. C. and a stretch ratio of 1.25.times. to 2.5.times. in both directions. The resulting product is a film of excellent properties such as surface smoothness, light transmission, low haze, low color, high elastic modulus and curl relaxation after aqueous processing. The melt cast film is useful as a photographic roll film to replace solvent cast cellulose triacetate.

摘要： A new process for foaming cellulose acetate rods consists of blending the cellulose acetate with a suitable plasticizer, a nucleating agent, cyclic ethylene carbonate, and a co-reactant for the ethylene carbonate and extruding into a foamed rod. Suitable co-reactants include aromatic diol polyesters, polycarbonates, and poly(ester-carbonates) and monomeric or polymeric materials containing the ##STR1## group, which have melting or flow points of less than about 250.degree. C.

摘要： Low-density microcellular foam having a cell size of not greater than 2 .mu.m and method of making by dissolving cellulose acetate in an acetone-based solvent, gelling the solution in a water bath maintained at 0-10.degree. C for a selected period of time to allow impurities to diffuse out, freezing the gel, and then freeze-drying wherein water and solvents sublime and the gel structure solidifies into low-density microcellular foam. The foam has a density of 0.065 to 0.6.times.10.sup.3 kg/m.sup.3 and cell size of about 0.3 to 2 .mu.m. The small cell size foam is particularly adaptable for encapsulation of laser targets.

摘要： Foam encapsulated laser fusion targets are made by positioning a fusion fuel-filled sphere within a mold cavity of suitable configuration and dimensions, and then filling the cavity with a material capable of producing a low density, microcellular foam, such as cellulose acetate dissolved in an acetone-based solvent. The mold assembly is dipped into an ice water bath to gel the material and thereafter soaked in the water bath to leach out undesired components, after which the gel is frozen, then freeze-dried wherein water and solvents sublime and the gel structure solidifies into a low-density microcellular foam, thereafter the resulting foam encapsulated target is removed from the mold cavity. The fuel-filled sphere is surrounded by foam having a thickness of about 10 to 100 .mu.m, a cell size of less than 2 .mu.m, and density of 0.065 to 0.6 .times. 10.sup.3 kg/m.sup.3. Various configured foam-encapsulated targets capable of being made by this encapsulation method are illustrated.
