A composition of matter suitable for solidifying radioactive wastes is formed of unsaturated polyester resins comprising a polyester (I) obtained polycondensing (a) maleic anhydride and/or maleic and/or fumaric acid, (b) isophthalic and/or terephthalic acid, (c) neopentylglycol, (d) optionally one or more conventional glycols, wherein the amount of (c) is at least 50% by moles, with respect to (c)+(d); another polyester (II) obtained polycondensing (a) maleic anhydride and/or maleic and/or fumaric acid, (b) isopropylidene-bis-(phenylene-oxypropanol-2), (c) optionally one or more conventional glycols, wherein the amount of (b) is at least 50% by moles with respect to (b)+(c); an ethylenically unsaturated monomer (III) capable of copolymerizing with (I) and (II); inhibitors, initiators, accelerators, glass fibers and other conventional additives and fillers the weight ratio of component (I) to (II) being from 100:0 to 20:80.
