Benzoin-treated NCO-terminated polyols, derived from HO-terminated poly (ethylene adipate), toluene diisocyanate (TDI) and benzoin (Scheme 24), have been used [102] as photoinitiators of oligomeric urethaneacrylale and epoxyacry-late formulations to give crosslinked films with improved physical properties due to a reduced content of low-molecular-weight compounds. 

Crosslinked films were prepared from these PDMS-b-PEO copolymers by hydrosilylation reaction between the terminal vinyl groups and multi hydride functional poly(dimethyl-co-methylhydride siloxane) (9), which was a commercial sample from Bayer (CA 730). A Si-H/vinyl ratio of 3 was used. Again Pt(0) was used as a catalyst and ethynyl cyclohexanol as an inhibitor, which prohibited curing before raising the temperature to 115 °C.

So, the PVA/poly(sodium styrene sulphonate) [PSSNa] blend was obtained by casting aqueous solution of polymers mixture (PVA with Mw= 124,000-186,000 and HD=99% and PSSNa with Mw= 70,000). The resulted films were crosslinked with 1,2-dibromethane in gaseous phase. A semi-interpenetrating network (SIPN) in which polyelectrolyte (PSSNa) chains are trapped inside a based PVA network was obtained [44], A totally miscible blend with a very good film clarity and high mechanical resistance [44] resulted.
