Abstract
Disclosed herein is a polyurethane elastomer comprising the reaction product of: A) at least one aliphatic diisocyanate monomer; B) at least one high molecular weight polyol; C) at least one low molecular weight diol comprising an aromatic moiety; and D) at least one saturated diol curing agent. These elastomers are useful as components of golf ball covers.
