Abstract


In this thesis, monopolymer and block polymer of different molecular weight are synthesized by materials of start agent of allyL alcohol and ethylene oxide and propylene oxide.A suitable techniques routine for the synthesise of above allyl alcohol alkoxylate is found. The different factors of the reaction temperatures the beginning pressure, catalyst and catalyst concentration, even H202 concentration and active carbon concentration are studied.In addition, the quaternary ammonium salt of allyl alcohol alkoxylate is prepared.At last, the properties of these products, the physical appearance, acid number, bydroxyl group value and iodine value are tested.
