Abstract
A polymerizable liquid composition is disclosed, intended for preparing polymerizates having outstanding optical and physical properties, said composition consisting of a bis (allylcarbonate) of a dihydric alcohol oligomer, a bis (allylcarbonate) monomer of a dihydric or a trihydric alcohol, or an allyl ester, or a triallyl cyanurate or isocyanurate, and an acrylic or vinylic monomer, said composition being polymerized in bulk with the aid of at least one radicalic initiator. Highly transparent articles are obtained, which are very useful for fine optical applications.
