The ECORS Pyrenean deep seismic profile and the overall structure of an orogenic belt

An alkali metalated acetylene-conjugated diene random copolymer obtained by reacting an acetylene-conjugated diene random copolymer having an acetylene unit content of 5-60 mol% and a block character P of 0.8-1.2 with an alkali metal or an organo alkali metal compound. The alkali metalated copolymer can be used as a starting material of functional polymers, graft polymers with vinyl monomers and monomer addition products, which are useful raw materials for the production of coating compositions, adhesives, reactive softeners and other industrial materials.
