synthesis of isomeric dihydroxyl spiroorthocarbonates (SOC-DIOL) and a hydroxyl hemi-spiroorthocarbonate (SOC-OL) is reported. The SOC-OL displayed a plasticization effect when compounded with an epoxy resin derived from bisphenol-A resulting in a decrease of T g . The analysis of volume change revealed that the SOC-OL reduced by 78% the level of shrinkage in comparison with the polymer where this additive
