Soil release polymers

A linear soil release polymer with the formula (I): X-[(EO)q-block-(PO)p]-[(A-R1-A-R2)n]-A-R1-A-[(PO)p-block-(EO)q] -X (I) where the linking moieties A are esters, where the R1 moieties are 1,4-phenylene moieties, where the R2 moieties are substituted ethylene moieties having C1-4 alkyl substituents...

Zusammenfassung:	A linear soil release polymer with the formula (I): X-[(EO)q-block-(PO)p]-[(A-R1-A-R2)n]-A-R1-A-[(PO)p-block-(EO)q] -X (I) where the linking moieties A are esters, where the R1 moieties are 1,4-phenylene moieties, where the R2 moieties are substituted ethylene moieties having C1-4 alkyl substituents, where the EO blocks are 100% ethylene oxide (CH2CH2O), where the PO blocks are 100% propylene oxide (CH2CH(CH3)O), where p is a number from 11 to 60, preferably from 15 to 50, more preferably from 20 to 40, most preferably from 25 to 35, where q is a number from 6 to 120, preferably 18 to 80, most preferably 40 to 70, provided that q is greater than p and preferably q is at least 1.5 times as large as p, where X is a capping moiety selected from C1-4 alkyl, branched and unbranched, and where n is a number from 2 to 16.
