Three series of poly(alkyleneglycol)diacrylates, namely poly(ethyleneglycol), poly(propyleneglycol) and poly(tetramethylene ether glycol)diacrylates, having M_n in the range 200-2000, have been prepared by acrylation of the corresponding bis-OH terminated oligomers. The synthesis conditions were investigated in order to obtain acrylic functionality very close to two. The oligomers were subjected to UV curing as thin films reaching complete double bond conversion in all cases with the exception of the lowest MW oligomers. Amorphous, crosslinked, rubbery films were obtained; their properties have been evaluated and correlated to the structure, the MW and functionality of the used oligomers. Thermal, dynamic-mechanical and swelling properties of the networks formed after the UV curing process are reported and discussed.
