Abstract: | Abstract A novel synthesis of 1-propenyl ether functionalized siloxanes has been achieved by the controlled, rhodium-catalyzed, chemoselective hydrosilation of 1-allyloxy-4(1-propenoxy)butane (APB) with various H-functional siloxanes. Chemoselective hydrosilation using a variety of Si—H functional siloxanes proceeds exclusively at the allyl ether group of the APB without participation at the 1-propenyl ether group. The electron-beam-induced cationic polymerization of these monomers in the presence of a diaryliodonium salt was studied and found to take place very rapidly and at very low radiation doses. |
