Abstract: The present invention provides a soil release polyester polymer which is biodegradable and has favorable soil releasing performance. In another aspect the invention also provides a cleaning composition comprising the same.

Abstract: The present disclosure relates to a polyamide comprising at least one repeating unit of formula I: —[OC—Ar—O—P(?O)(—Ar)—O—Ar—CO—NH—R—NH]— Formula (I) wherein, Ar is independently selected from the group consisting of aryl, arylene, heteroaryl and carbocyclic group; R represents a covalent bond or a divalent hydrocarbon-based group selected from the group consisting of saturated or unsaturated aliphatics, saturated or unsaturated cycloaliphatics, aromatics, arylaliphatics, and alkylaromatics.

Abstract: The invention pertains to an improved branched glycolic acid copolymer, comprising recurring units derived from an aromatic dicarboxylic acid, which has an appropriate rheological profile so as to be successfully used in combination with standard polyester resins for obtaining multi-layer containers having thin barrier layers.

Abstract: The present disclosure relates to a polyamide comprising at least one repeating unit of formula I: —[OC—Ar—O—P(=0)(—Ar)—O—Ar—CO—NH—R—NH]— Formula (I) wherein, Ar is independently selected from the group consisting of aryl, arylene, heteroaryl and carbocyclic group; R represents a covalent bond or a divalent hydrocarbon-based group selected from the group consisting of saturated or unsaturated aliphatics, saturated or unsaturated cycloaliphatics, aromatics, arylaliphatics, and alkylaromatics.

Abstract: The invention pertains to an improved method for synthesizing a branched poly(hydroxyl acid) polymer comprising effecting polycondensation reaction of a monomer mixture comprising: (i) at least one hydroxyl acid having only one hydroxyl group and only one carboxylic acid group [hydroxyacid (A)]; (ii) at least one polyol comprising at least three hydroxyl groups and being free from carboxylic acid group [polyol (H)]; (iii) at least one polyacid comprising at least three carboxylic acid groups and being free from hydroxyl groups [polyacid (O)]; and (iv) at least one carboxylic acid having one or two carboxylic acid groups and being free from hydroxyl group [acid (C)], wherein the amount of said acid (C) is such that the number of carboxylic acid groups thereof is comprised between 0.0001 to 0.010% with respect to the number of hydroxyl groups of hydroxyacid (A).

Abstract: The present invention relates to components of mobile electronic devices made of an amorphous polyamide composition characterized by excellent mechanical properties, low moisture uptake, low distortion and very good aesthetical properties. The amorphous polyamide has recurring units derived from the polycondensation of a mixture of monomers of aromatic dicarboxylic acid(s), cycloaliphatic diamine(s) with 6 to 12 carbon atoms, and a third monomer with 10 to 16 carbon atoms.
