Document Type and Number:
Japanese Patent JP2002520477
Kind Code:
A
Abstract:
The invention concerns a terephthalic polyester composition (CPT), comprising in mixture: an ethyleneterephthalate homooligomer (PET 1) essentially containing recurrent terephthalate oxyethylene (TE) units; and a block terephthalate copolymer (PET 2/TE-POE) containing at least a polyethyleneterephthalate (PET 2) sequence; and at least a terephthalate polyoxyethylene (TE-POE) sequence whereof the POE unit has a molecular mass of 1500 to 4000 in number; said composition (CPT) being characterised in that: the quantity of (TE) units of (PET 1) represents not more than 10% of the total number of (TE) units present in said composition (CPT); the weight quantity of (TE) units present in the composition (CPT) represents at least 10% of (TE) units present in the composition (CPT); the quantity by weight of mono(oxyethyleneoxy) radicals (OEO) represents at least 1.3% of the weight of the composition (CPT), said radicals (OEO) belonging to the aromatic diester oxyethylene groups (ODA) of formula: -A-C(O)-O-CH2-CH2-O-C(O)-A- present in all the (PET 1) and (PET 2) sequences; and the molar mass by weight of block terephthalic copolymer (PET 2/TE-POE) is at least 30000. The invention also concerns the use of said composition as soil release agent in detergent formulations for washing textiles.
