Abstract: This invention provides a novel process for preparing soluble phthalocyanines by microwave irradiation in the absence of any organic solvent. Three different starting materials, i.e. t-butylphthalic anhydride, t-butyl phthalonitrile and metal-free H2Pc (tetra-t-butylphthalocyanine) have been adopted , respectively. The starting material with proper metal compound, such as chloride or acetate were irradiated in a commercial microwave oven for a period of 1 to 30 minutes at a power of 200˜900 W. This process is noted to reduce drastically reaction time of MPc formation from 8˜24 hours to 10˜30 minutes due to its unique heating by microwave irradiation. Sandwiched type MPc2(such as Lu Pc2) can be produced only through metal replacement from metal-free phthalocyanine by microwave irradiation.

Abstract: A crosslinkable aqueous polyester-containing emulsion and a process for preparing the same. The emulsion is obtained by polymerizing unsaturated monomers of acrylic, using a crosslinkable, sulfonated polyester emulsifier having an acid number less than 80 mg KOH/g and an intrinsic viscosity greater than 0.1 dl/g as an emulsifier. The emulsion has the chemical characteristics of both polyester and acrylic resin, i.e. has low volatile organic compounds, good mechanical stability, and good storage stability. Since the emulsion is crosslinkable, a film formed by the emulsion has excellent adhesion, water and heat resistance. Thus, the emulsion is useful for coating and printing on Nylon, PET, OPP films, as well as for high performance industrial surface coating and adhesion for which good heat-, water-, and weather-resistance are required.

Abstract: A method for the preparation of metallic salts of fatty acids comprising the steps of: (a) reacting alkali hydroxide with a fatty acid in a saponification reaction to form an alkali soap; (b) reacting the alkali soap with an aqueous metallic salt solution in a double decomposition reaction to cause the production of metallic fatty acid salt; (c) performing at least one cycle of an alternating alkalinization-acidization reaction by adding an aqueous alkali hydroxide solution to the metallic fatty acid salt to raise the solution pH, followed by adding an acidic aqueous salt solution contain the same metal ions to lower the solution pH. High purity metallic salts of fatty acids can be obtained without a solvent washing step and the metallic fatty acid salts prepared from this invention can be effectively used as photolyzing agent to initiate and/or accelerate the photo-degradation of plastics.

Abstract: A composition of matter including a polymeric material which is either a plastic having carbon to carbon linkages or a binary blend of the plastic and starch, in which the plastic is at least 25% by weight of the binary blend; and an organic peracid compound dispersed in the polymeric material, the quantity of the peracid compound being 0.1 to 10% by weight of the polymeric material.
