Synthesis and characterization of α-butyl-ω- { 3-(2,2-dihydroxymethyl)- propionyloxy } propylpolydimethylsiloxanes

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 carried out and objective products could be achieved.
