Abstract: The present invention relates to a method for chemically adhering a diene rubber to a piezoelectric polymer, the method comprising the steps of: a) providing a piezoelectric polymer having at least one surface, b) providing a rubber component having at least one surface and comprising a sulfur cross-linkable rubber composition, c) introducing oxygen-containing functional groups on the at least one surface of the piezoelectric polymer, d) reacting the oxygen-containing functional groups with a compound comprising thiocyanate groups, and e) contacting the surface of the piezoelectric polymer obtained of step d) with the surface of the rubber component, and cross-linking.

Abstract: The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. The cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ?10 phr to ?20 phr of a natural rubber or an isoprene rubber or a combination thereof; a filler; a resin, and first and second coupling agents, wherein the first coupling agent is a mercaptosilane and the second coupling agent is a silane selected from a disulfide silane, a tetrasulfide silane, or a combination thereof, wherein the rubber composition comprises ?80 phr to ?90 phr of a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group, and wherein the weight by weight ratio of the mercaptosilane to the silane is in a range of ?2:1 to ?4:1.

Abstract: A cross-linkable rubber composition may include, per hundred parts by weight of rubber (phr): 100 phr of a blend of a natural rubber (NR), a polybutadiene rubber (BR), and first and second solution polymerized styrene-butadiene rubbers (SSBR); a silica filler, a resin, and ?1 phr to ?20 phr of first and second coupling agents, wherein the first coupling agent is a mercaptosilane and the second coupling agent is selected from a disulfide silane, a tetrasulfide silane, or a combination thereof.

Abstract: The present invention relates to a cross-linkable rubber composition, the cross-linkable rubber composition comprising, per hundred parts by weight of rubber (phr): 100 phr of a rubber component comprising a natural rubber or an isoprene rubber or a combination thereof, a white filler, and a black filler. The white filler is a mixture of a first white filler and a second white filler, wherein the first white filler has a BET surface area of 170 m2/g to 180 m2/g measured according to ASTM D6738 and/or the second white filler has a BET surface area of 5 m2/g to 10 m2/g measured according to ASTM D5604.

Abstract: The present invention relates to a cross-linkable rubber composition, the cross-linkable rubber composition comprising a natural rubber (NR), a filler, and a resin. The resin is a terpolymer of ethylene, acrylic ester and maleic anhydride and is present in an amount ranging from ?5 to ?20 phr.

Abstract: It is provided a pneumatic tyre, the tyre having a circumferential direction, an axial direction and an equatorial plane, and the tyre comprising: a tread extending in a tyre circumferential direction, said tread comprising at least one circumferential groove running continuously in the circumferential direction, and a plurality of axial grooves or transverse grooves running at an angle to the axial direction, and a plurality of blocks defined by the circumferential groove and the axial grooves or transverse grooves, said blocks extending radially between an inner surface of the tread and a tread surface to come into contact with the ground, wherein at least some of the blocks comprise at least one wavy groove that extends from a circumferential groove inwardly into the block, and wherein the wavy groove has a depth extending radially from the tread surface to come into contact with the ground towards the inner surface that ends above the inner surface (26) of the tread.
