Abstract
Abstract SHOCK-RESISTANT RESIN AND METHOD FOR THEIR PREPARATION ABSTRACT OF THE DISCLOSURE . -Improved shock-resistant resins are obtained by graft-copolymerizing a monomer selected from among alkenyl aromatics, vinylics, acrylics, their halogenated derivatives or admixtures of same, with maleic anhydride and/or an imide derivative of such anhydride and with a terpolymer composed by ethylene, a higher homolog of ethylene and a polyene having at least one system of conjugated double bonds.
