    Abstract: Methods for preparing water soluble, non-peptidic polymers carrying carboxyl functional groups, particularly carboxylic acid functionalized poly(ethylene glycol) (PEG) polymers, are disclosed, as are the products of these methods. In general, an ester reagent R(C═O)OR′, where R′ is a tertiary group and R comprises a functional group X, is reacted with a water soluble, non-peptidic polymer POLY-Y, where Y is a functional group which reacts with X to form a covalent bond, to form a tertiary ester of the polymer, which is then treated with a strong base in aqueous solution, to form a carboxylate salt of the polymer. Typically, this carboxylate salt is then treated with an inorganic acid in aqueous solution, to convert the carboxylate salt to a carboxylic acid, thereby forming a carboxylic acid functionalized polymer.

    Abstract: A process for selectively modifying pendent functionalities of a polymer containing the pendent functionalities and hydrolytically unstable backbone functionalities is provided. The process includes: (a) providing the polymer in a solvent system (preferably an ether-containing solvent system) adapted to maintain the polymer in a dissolved or partially dissolved state, wherein the pendent functionalities of the polymer are more accessible than the hydrolytically unstable backbone functionalities; and (b) adding at least one additive to the solvent system to selectively modify at least one of the pendent functionalities. The process is especially well suited for specifically acid hydrolyzing pendent esters of PDTE.

    Abstract: A method for treating a polyester polymer according to the present invention is to heat a polyester polymer (C), which is obtained by ring-opening polymerization of a polymer (A) having hydroxyl and/or ester bonds and cyclic esters (B) containing ε-caprolactone, in a solid state at a temperature that is not lower than 115° C. and lower than 170° C. and is lower than the melting point of the polyester polymer (C) in order to remove an organic low-boiling component (v) from the polymer (C) obtained by the polymerization. According to the present invention, there is obtained a polyester polymer in which ε-caprolactone and caprolactone dimer in polyester polymers are fully removed without causing deterioration or change of the physical properties of resins and further without causing deterioration of their colors and a decrease in cost effectiveness.

    Abstract: The present invention provides a biodegradable recycled polyester resin and a production process therefor, wherein the polyester resin is inexpensive and economical due to use of recycled aromatic polyesters, and further, can solve problems of wastes by affording biodegradability to the aromatic polyester which has so far been assumed to have no biodegradability. The biodegradable recycled polyester resin, according to the present invention, is obtained by a process including the step of carrying out a reaction of a recycled aromatic polyester (A) with an aliphatic polyester (B) having a number-average molecular weight of 3,000 to 300,000 in a reaction ratio (weight ratio) of (A)/(B)=95/5 to 5/95, thereby affording biodegradability to the recycled aromatic polyester (A).
