Silicone containing copolymers: Synthesis, properties and applications

Abstract

A comprehensive survey of the recent developments on the synthesis, properties and applications of silicone containing copolymers is provided. Influence of (−R 2 Si−O−) backbone composition on the physicochemical properties of silicone copolymers, such as thermal transitions, solubility parameter and surface tension is discussed. Preparation and properties of well-defined α,ω-reactive organofunctionally terminated (telechelic) silicone oligomers and their utilization in the preparation of a wide range of block and segmented copolymers through step-growth,anionic, ring-opening and living free-radicalpolymerization techniques are provided. Use of silicone oligomers in the modification of polymeric network structures is also discussed. Special emphasis is given to the discussion of the effect of silicone oligomer and organic segment structure and molecular weight on the morphology and surface and bulk properties of the resultant silicone containing copolymers and networks.

Silicone-urethane membranes for lithium batteries. Part 1. Moisture-cured poly(siloxane-urethane-urea) elastomers containing polyethylene oxide (PEO) segments - synthesis and characterization as potential membrane materials

“…Silicone-urethanes 1 are specific class of polymers that are characterized by excellent mechanical properties of polyurethanes while having certain features specific for silicones, like low surface-free energy or semi-permeation ability. Because of those unique characteristics, silicone-urethanes, specifically moisturecured, have been tested widely as specialty coatings, elastomers for medical applications, or semi-permeation membranes.…”

Ultralow Friction with Hydrophilic Polymer Brushes in Water as Segregated from Silicone Matrix

“…[ 32 ] Its synthesis by hydrolysis of the corresponding tert -butyl-or trimethylsilyl-protected precursors, which in turn are obtained by group transfer polymerization, has been proposed. [ 33 ] However, it must be pointed out that the hydrolysis of PDMS-b -poly( tert-butyl acrylate) (PDMS-b -P t BA) by p -toluene sulfonic acid or NaI/Me 3 SiCl resulted in either scission of the PDMS block or incomplete deprotection.…”
