Abstract: Ceramic green tape formulations are described comprising critical amounts of a ceramic powder, poly(propylene carbonate) as the binder, a solvent mixture and a plasticizer. These ingredients are admixed to yield a slurry having a Brookfield viscosity in the range of about 500 to 4500 cps at 25.degree. C. The slurry is cast into a thin film on a substrate, the solvent mixture is removed from the film and the green tape is removed from the substrate. The poly(propylene carbon)-based green tapes have been shown to have tensile strengths of greater than 35 psi and flexibility which would permit successful punching of register and feed-through (via) holes and screen printing. The green tapes of this method are easily laminated to produce multilayered capacitors and other multilayered structures having ceramic contents well in the range generally considered desirable for ceramic processing.

Abstract: Zinc carboxylate catalysts for the copolymerization of carbon dioxide and epoxides are prepared by the reaction of zinc oxide with glutaric or adipic acid in an aprotic reaction solvent. Azeotropic distillation may be used to separate the water-solvent phase from the reaction mixture, or the catalyst may be separated from the reaction mixture by filtration and drying, generally without the need for repeated washings to remove active hydrogen atom sources. Examples of aprotic reaction solvents are toluene, dibutyl ether, anisole and ethyl benzoate.

Abstract: Poly(alkylene carbonates) of controlled molecular weight are made by copolymerizing carbon dioxide and one or more oxirane compounds using zinc polycarboxylate catalyst in the presence of a sterically hindered organic proton donor. The acidity of the donor is in the range of 3 to 20 pK.sub.a and the steric quality of the donor is such that it has a steric parameter (E.sub.s) of -0.38 or less. The molecular weight of the polymer can be regulated by altering the level of proton donor over a range which does not adversely affect catalyst productivity. Benzoic acid and phenol are examples of suitable proton donors. The preferred catalyst is one made from zinc oxide and a dicarboxylic acid, such as glutaric acid or adipic acid.
