ABSTRACT:
A slow speed wheel with high abrasion resistance, good riding attributes and excellent bounce from a composition comprising at least 20 wt % of a segmented thermoplastic copolyester or a blend of copolyesters consisting of essentially of a multiplicity of recurring long chain ester units and short chain ester units joined head-to-tail through ester linkages, said long chain ester units being represented by the formula (A): ##STR1## and said short chain units being represented by the formula (B): ##STR2## wherein said short chain ester units make up between about 10 to about 95 wt % of said copolyester or blend of copolyesters; G is a divalent radical remaining after the removal of terminal hydroxyl groups from a polyether glycol copolymer based on poly(propylene oxide) and poly(ethylene oxide); R is a divalent radical remaining after removal of carboxyl groups from a aromatic dicarboxylic acid; D is a divalent radical remaining after removal of hydroxyl groups from a diol.
