【Abstract】 Changing the EO/PO ratio,the molecular weight and the arrangement of EO and PO unit was studied. With raising the EO/PO ratio, the copolymer could point, viscosity and surface tension will increase. When the molecular weight rises, its viscosity will increase greatly, and foaming ability becomes better. With block copolyether’s forming, the cloud point lowers appreciably.更多还原
