摘　　要：A series of polydimethylsiloxanes containing two primary hydroxyl groups at one single chain end were synthesized by five-step reactions which included esterification,hydroxyl protection,anionic ring-opening polymerization,hydrosilylation and deprotection.The prepared compounds in each step were characterized.The results showed that each step synthesis was successfully carded out and objective products could be achieved.
