Claim:
1. A hard-surface polishing material comprising: hard segments; soft segments; from 0 wt % to about 80 wt % filler material, and one or more of a foaming agent and a cell stabilizer, wherein a weight ratio of the hard segments to the soft segments is greater than or equal to 0.95:1, and wherein the weight ratio of the hard segment to the soft segments is calculated by defining the hard segments to be the molecular weight of an aromatic portion of a polymer structure plus the 60 to 150 Da of an oligomeric portion of the polymer structure minus the molecular weight of a diol and/or an amine and an isocyanate (N═C═O) portion of the polymer structure, and the soft segment is defined as a 150 to 6000 Da portion of the polymer structure.
