Abstract: An aliphatic copolyester having a plurality of first ester units of the formula : - CO - [R 1 ] t - CO - O - R 2 - O - wherein R 1 represents a divalent aliphatic group, R 2 represents a divalent aliphatic and t is an integer of 0 or 1, and a plurality of second ester units of the formula: wherein R 1 and t are as defined above and R 3 represents an aliphatic group. The molar ratio of the first ester unit to the second ester unit is 90:10 to 99.9:0.1. The copolyester is produced by reacting an aliphatic diester e.g. dimethyl succinate with an aliphatic glycol e.g. 1,4 butanediol and with a monoacylated glycerin and with a monoacylated glycerin e.g. glyceryl a -monolaurate under ester exchanging conditions.

Abstract: PURPOSE:To provide an electrode having improved selectivity to oxidation reaction by coating a metal oxide supporting graphite plate with a pyrrole or thiophene polymer film by electrolytic polymn. CONSTITUTION:A metal oxide supporting graphite plate is immersed as the anode in a soln. contg. pyrrole or thiophene and perchlorate or borofluoride, and electric current is supplied by a prescribed quantity (about 0.1-10C) to coat the graphite plate with a pyrrole or thiophene polymer film by electrolytic polymn. Thus, a metal oxide supporting graphite electrode is obtd. The electrode is advantageously applicable to the electrode oxidation reaction of aromatic hydrocarbon.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester excellent in mechanical strength and fabricability and having a novel structure by subjecting an aliphatic dicarboxylate, an aliphat ic glycol and monoacylated glycerin to condensation reaction. SOLUTION: The polyester is obtained by subjecting an aliphatic dicarboxylic acid represented by formula III (wherein R1 is an 1-12C divalent aliphatic group; R4 and R5 are each an 1-4C alkyl group; and t is 0 or 1), an aliphatic glycol represented by formula IV (wherein R2 is a 2-12C divalent aliphatic group) and a monoacylated glycerin represented by formula V (wherein R3 is a 6-22C aliphatic group) to condensation reaction. The amount of the component of formula V is 0.001-0.10 mol per 1 mol of the sum of the components of formulas III and IV. By the condensation reaction is obtained a biodegradable aliphatic polyester having a number average molecular weight of 10,000-1,000,000 comprising an ester portion A represented by formula I (wherein p is a molar ratio of the ester portion of the polyester) and an ester portion B represented by formula II (wherein (r) is a molar ratio of the ester portion of the polyester), the molar ratio (r) of the ester portion B being in the range of 0.001-0.10.

Abstract: PROBLEM TO BE SOLVED: To obtain a novel polystyrene-supported chalcogenocyanate which consists of a polystyrene containing styrene units having a chalcogenocyanate group and is useful as a reaction reagent. SOLUTION: This polystyrene-supported chalcogenocyanate has units of formula I. It is obtained by reacting a potassium chalcogenocyanate and a polystyrene containing units of formula II in a solvent. In the formulas, R1 is a bivalent hydrocarbon; R2 is a bivalent aliphatic group; Ar is an arylene; Z is a bivalent coupling group consisting of a hetero atom or carbonyl; X is a chalcogen atom; Y is a halogen; and s, t, and n are each 0 or 1. Preferably, the polystyrene containing styrene units of formula II is in the form of spherical beads of 400-200 μm (100-400 mesh). A corresponding nucleophilic chalcogen reagent is obtained by reacting a reducing agent such as lithium borohydride or the like in a solvent such as tetrahydrofuran or the like.
