*和至少一种通式
-C(O)-A-C(O)-O-CH2-CH2-O-(CH2-CH2-O)n-
的聚氧乙烯对苯二甲酸酯嵌段(TE-POE),n的数值为使得所述嵌段的数均分子量约为1500至4000,优选约为3000至4000,

*检测A(对苯二甲酸)芳核的存在,
*测定在聚对苯二甲酸酯组合物(TPC)中对苯二甲酸乙二醇酯均聚低聚物(PET1)的百分比,
·对苯二甲酸乙二醇酯均聚低聚物(PET1)的信号出现在1000至5000之间(以聚苯乙烯等同物表达的质量);

*芳(对苯二甲酸T)核,
*氧乙烯单元,

测试
□预洗涤:
将下述物质的尺寸为10×10cm的无粗糙度方块在振荡式涤垢仪在40℃下用含0.5wt%所测试的去污聚合物活性物质的洗涤剂配剂预洗涤20分钟;所使用的水的硬度为30℃HT;洗涤剂用量为每1升水5克,所述物质为:
*聚酯Style 777 100% Dacron Type 54(Disperse Dyeable),由Touzart&Matignon制造,
*和聚酯/棉(67/33),由CFT(测试物质中心)制造。
随后所述方块织物在冷水(14℃)中漂洗3次,每次5分钟,然后两次经过抛光机进行干燥。
□沾污:
将4滴脏机油(DMO)沉积在经预洗涤的试样上。
为保证所述污渍牢固地粘附,将所述织物在60℃烘箱中放置1小时。
为使结果具有良好的再现性,所述织物在24小时之内进行洗涤。
□洗涤:
在与预洗涤相同条件下进行洗涤(在40℃下20分钟,每1升30°HT的水使用5克含1%去污聚合物活性物质的洗涤剂,然后用冷水漂洗3次,每次5分钟,并在抛光机下进行2次干燥操作)。
评价
使用Dr.Lange/Luci100色度计测量在洗涤前后所述织物的反射系数。
作为去污剂被测试的聚合物的效力通过除去污渍的%来评定,通过如下公式来计算:
以%计的E=100×(R3-R2)/(R1-R2)
R1代表未染污的织物在洗涤前的反射系数;
R2代表染污的织物在洗涤前的反射系数;
R3代表染污的织物在洗涤后的反射系数。
对每种测试的产物计算除去污渍的平均%。
