Abstract: Firstly,allyl polyglycerin ether (APGE),as intermediate,was synthesized with allyl glycidyl ether (AGE) and diglycerol (DGY) as starting materials and KOH as catalyst.Then the APGE was hydrosilylated with polyhydromethyl siloxane (PHMS) in the presence of hexachloroplatinic acid as catalyst and isopropanol as solvent to form a kind of polyglycerol modified polysiloxane (APGE-PHMS) as the targeted product.Structure of the intermediate as well as the targeted product was characterized and the surface activity,adsorption performance and spread out performance of APGE-PHMS were investigated.The surface activity of the aqueous solution of the targeted product at 25 ℃ shows cmc 144.1 mg/L and γcmc 23.0 mN/m.When mass concentration of the aqueous solution of the targeted product achieves 4 multiples of its cmc,the dynamic contact angle over paraffin surface at temperature of 25 ℃ can be reduced to 23°.

Key words: polysiloxane, polyglycerol, surface activity
