摘要

A process for the catalytic hydrogenation of block copolymers having at least one non-elastomeric polymer block and at least one elastomeric polymer block, characterized in that the block-limestone flake has the general configuration ** See formula) ** wherein each block A is a mono- α-alkinal-arene photopolymer block and each block B is a random flake block of at least one conjugated design and at least one mono-alkaline-arene, each block A having a average molecular weight comprised between approximately 3,000 and 60,000, and each block B having an average molecular weight comprised between 25,000 and 300,000, and subsequent to hydrogenation, 0 to 25% of the double bonds of the arene have been reduced and reduced at least 90% of the aliphatic double bonds.
