Abstract:
A rubber compound for making a pneumatic tyre structural component comprising a cross-linkable unsaturated-chain polymer base, a reinforcing filler, a thermosetting resin and a vulcanization system. The thermosetting resin comprises functionalized lignin with —OR groups wherein R is an alkyne group with a number of carbon atoms of between (3) and (18).
