Patent ID: 7259209

Claim:
A blend of reactive thermoplastic polymer particles which comprises: a) a first portion of the particle blend comprises thermoplastic polymers with reactive groups selected from the group consisting hydroxyl groups, amino groups, carboxyl groups, carboxylic anhydride groups, mercapto groups, silane groups, hydrosilyl groups and mixtures thereof, said thermoplastic polymer comprising a block copolymer selected from the group consisting of styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene, styrene-isoprene-styrene, styrene-ethylene-butylene-styrene and styrene-ethylene-propylene-styrene, and mixtures thereof; b) a second portion of the particle blend comprises (i) thermoplastic polymers with reactive groups selected from the group consisting of isocyanate groups, epoxide groups and reactive olefinically unsaturated double bonds, (ii) thermoplastic polymers containing water-binding fillers or (iii) mixtures thereof; and c) optionally the blend particles contain auxiliaries and additives which do not react with the functional polymers of the a) and b) particles as a part of the particle a), b) or both or as separate particles; wherein said blend is in the form of granules, said granules having a mean particle size from 0.5 millimeter (mm) to 40 millimeter (mm).
