Synthesis and characterization ofα-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 carded out and objective products could be achieved.
