摘要： Molded articles with improved physical characteristics are obtained under molding conditions for general resin without causing deformation at the mold releasing time if a composition containing aliphatic polyester resin and one or more metal salts of aromatic sulfonate of a specified kind is used. Such a composition is placed inside a mold maintained at a temperature below the crystallization-initiating temperature by differential scanning calorimetry and above the glass transition temperature is molded while it crystallizes.

The molar concentration of one of the L-lactic acid units and D-lactic acid units in a lactic acid component of the polylactic acid type biodegradable resin is in the range between about 75 mol % and about 98 mol %. The terpene-phenol copolymer may include at least one composition selected from the group consisting of: (a) cyclic terpene-phenol copolymer, prepared by copolymerizing cyclic terpene and phenol; (b) cyclic terpene/phenol (1:2 molar ratio) addition product, prepared by adding two molecules of phenol to one molecule of cyclic terpene (c) polycyclic terpene/phenol (1:2 molar ratio) addition product, prepared by a condensation reaction of the cyclic terpene/phenol (1:2 molar ratio) addition product with one of aldehyde and ketone, and (d) polycyclic terpene/phenol (1:1 molar ratio) addition product, prepared by a condensation reaction of a cyclic terpene/phenol (1:1 molar ratio) addition product with one of aldehyde and ketone.

摘要： A lactic acid based by-product formed in a process of producing a lactic acid based composition is subjected to racemization in the presence or absence of a catalyst to thereby obtain a lactic acid component having substantially optical inactivity. Then, lactide or polylactic acid having optical inactivity can be obtained from the lactic acid component having the optical inactivity. The obtained lactide or polylactic acid is mixed with lactide or polylactic acid having an optical purity in a range of 90 to 100% e.e. at a predetermined ratio to thereby obtain lactide or polylactic acid having a desired optical purity.
