    Abstract: A polyurethane foam-forming composition having a surfactant with the formula R13Si(OSiR2G)xOSiR33, where each R1, R2, and R3 is independently an alkyl radical having from 1 to 10 carbon atoms; G is a group having the formula —R4(OR5)yA, where R4 is a divalent alkyl radical having from 2 to 4 carbon atoms, R5 is ethylene or propylene, A is a hydroxyl group, and x is an number from 1 to 5, and y is an number from 0 to 10 is provided which can be used to form polyurethane foams having a large open cell concentration, improved dry and wet compression sets, and low fugitive emissions.

    Abstract translation: 一种具有式R 13 Si(OSiR 2)x OSi R 33的表面活性剂的聚氨酯泡沫形成组合物,其中每个R 1,R 2和R 3独立地是具有1至10个碳原子的烷基; G是具有式-R4(OR5)yA的基团,其中R4是具有2至4个碳原子的二价烷基,R5是乙烯或丙烯,A是羟基,x是1至5的数 ,y是0〜10的数,可用于形成具有大开孔浓度,改进的干湿压缩组和低逸散排放的聚氨酯泡沫。
