Abstract:
A mixture comprising a polymer of formula III and a hydrophilic polyester copolymer with repeating segments of ethylene terephthalate units containing 10-50% by weight of polyoxyethylene terephthalate units, derived from a polyoxyethylene glycol of average molecular weight of from about 300 to about 6,000, and the molar ratio of ethylene terephthalate units to polyoxyethylene terephthalate units in the polymeric compound is between 2:1 and 6:1, where formula III isR6â€”[OCH2CH(R3)]xâ€”Oâ€”C(&boxH;O)NHR1 wherein x is 4-100; R1 is C1-C24 alkyl, C1-C24 alryl, C1-C24 alkylaryl, or C1-C24 alkenyl; R2 is H or R1; R3 is H, CH3, or CH2CH3 wherein the ratio of (CH3+CH2CH3)/H in the repeat unit is greater than or equal to 6; and R6 is R2 or R1NHC(&boxH;O).
