去污聚合物
Abstract:
直链去污聚合物，具有式(I)：X-[(EO)q-嵌段-(PO)p]-[(A-R1-A-R2)n]-A-R1-A-[(PO)p-嵌段-(EO)q]-X (I)，其中连接部分A为酯，其中R1部分为1，4-亚苯基部分，其中R2部分为具有C1-4烷基取代基的取代亚乙基部分，并且R2部分包含衍生自2，3-丁二醇缩合的取代亚乙基部分，其中EO嵌段为100％氧化乙烯(CH2CH2O)，其中PO嵌段为100％氧化丙烯(CH2CH(CH3)O)，其中p为2至50的数字，优选5至45，更优选6至40，再更优选7至40，并且最优选8至40，甚至11至35；其中q为6至120的数字，优选18至80，最优选40至70，条件是q大于p，且优选地q为p的至少1.5倍大；其中X为合适的封端部分，优选选自支链的和无支链的C1-4烷基；其中n为2至16的数字。
Abstract(English):

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 moities, where the R2 moieties are substituted ethylene moieties having C1-4 alkyl substituents and the R2 moieties comprise substituted ethylene moieties derived from the condensation of 2,3 butane diol, 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 2 to 50, preferably from 5 to 45, more preferably from 6 to 40, yet more preferably from 7 to 40 and most preferably from 8 to 40, even from 1 1 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 suitable capping moiety, preferably selected from C1-4 alkyl, branched and unbranched; where n is a number from 2 to 16.
