Abstract: With a Pt catalyst, α,ω-hydrogenpolysiloxane reacted with allyl glycidyl ether to form an intermediate, α,ω-diepoxysiloxane and polycondensation of this intermediate and aminopolyalkyleneoxide yielded the silicone amino-polyalkykeneoxide block copolymer(BPEAS). Then, chemical structures of BPEAS were characterized using IR and 1H-NMR; the performance was determined and investigated using Kawabate Evaluation System (KES), and other instruments. The subsequent results showed that BPEAS could provide a bulky softness, good wettability, and anti-wrinkle property for the treated fabric without the emulsifier.
