Introduction

SD-7502,Using glycerin as initiator copolymerized with propylene oxide and ethylene oxide and terminated with ethylene oxide has a certain hydrophilic property. the characteristics are as follows:
1、 The molecular weight of about 8500 with a narrow molecular weight distribution coefficient the molecular weight distribution coefficient lower than 1.20.
2、 Terminated with ethylene oxide which accounting for 4%-8% with a certain reaction activity reducing the amount of the catalyst.
3、 Copolymerized with propylene oxide and ethylene oxide which accounted for the same quality with a certain hydrophilic property no crystallization at normal temperature. 4、 No BHT no amine products low odor significantly decreased the content of VOC.
