摘要： PROBLEM TO BE SOLVED: To provide a method for industrially inexpensively producing an aromatic polyester having high polymerization degree and excellent in heat resistance and mechanical characteristics so as to have excellent hue in a shot time by carrying out direct melt polymerization of a dicarboxylic acid with a diol without previously esterifying the dicarboxylic acid with the diol. SOLUTION: This method for producing an aromatic polyester by carrying out heat melt reaction of (a) a dicarboxylic component such as terephthalic acid with a diol component such as 2,2-bis(4-hydroxyphenyl) propane in the presence of a diarylcarbonate comprises carrying out the reaction in the presence of a specific pyridine-based compound and an alkali metal carbonate (hydrogen carbonate). The resultant aromatic polyester has >=0.6 dl/g reduced viscosity (measured in 1.2 g/100 ml concentration at 35 deg.C in phenol/1,1,2,2- tetrachloroethane mixed solvent (weight ratio: 60/40).

摘要： PROBLEM TO BE SOLVED: To provide the subject plaster produced by applying a drug-containing tacky adhesive layer to a substrate interposing a specific porous polyester elastomer film therebetween, having excellent adhesiveness to the skin and exhibiting increased capability to effect the transcutaneous absorption of a transcutaneous absorption drug. SOLUTION: A drug-containing tacky adhesive layer having a thickness of 1-30μm is applied to a surface of a substrate interposing a porous polyester elastomer film having a pare ratio of 10-95% between the adhesive layer and the core. The porous membrane is preferably composed of a polyester elastomer containing polybutylene 2,6-naphthalate as a hard segment and a polyoxytetramethylene glycol as a soft segment. The porous membrane is produced preferably by casting a solution composition composed of the polyester elastomer and a water-miscible polar solvent on a supporting substrate, making the cast film gel by cooling and extracting the solvent from the solution composition using an aqueous solvent. The water-miscible polar solvent is preferably e.g. N-methylpyrrolidone.
