Shrinkage and recyclability of poly(1,2-ethylene-bis(dimethylsiloxane))
Description: Non-shrinking polymers are desirable as encapsulants for strain-free packaging for electronics. Ring-opening polymerizations of cyclic monomers such as lactams, cyclic ethers, and cyclic oligosiloxanes have proven an effective strategy for reducing shrinkage. In this report the authors examined the loss of volume during the ring-opening polymerization of neat 2,2,5,5-tetramethyl-l-oxa-2,5-disilacyclopentane to give poly(1,2-ethylene-bis(dimethyl-siloxane)). Monomer 1 is under sufficient strain … more
