Two urethane dimethacrylates of oligomer type were prepared according to the general synthetic route shown in Scheme 1, via condensation of the poly(ethylene glycol) (PEG) with an aliphatic diisocyanate, such as IPDI, to yield a prepolymer with end isocyanate groups, which finally was converted to a dimethacrylate by the reaction with 2-hydroxyethyl methacrylate.
However, similar work using IPDI with different steric isomer ratios was not found in the literature.
First, urethane monoacrylate (IPDI-HEA) was obtained in a reaction between the secondary cycloaliphatic NCO group (NCOsec) of IPDI and the OH group of HEA with DBTDL as catalyst.
Polymerization of IPDI with PTMO or siloxane diols, and copolymerization of IPDI, PTMO, and siloxanes in a bulk system were performed in a differential scanning calorimeter (DSC2010, TA instrument).

Mixing and film formation were described before the reaction chemistry of polyols (polyacrylates, polyester/acrylic hybrids, and polyurethane dispersions) with polyisocyanates (HDI or IPDI hydrophobics and polyether- or sulphonic acid-modified hydrophillics) were described.
