1. An orthodontic article comprising a reaction product of a polymerizable composition comprising:
30-65 parts by weight of at least one monofunctional (meth)acrylate monomer per 100 parts of the polymerizable composition,
wherein the at least one monofunctional (meth)acrylate monomer is selected from a group comprising at least one of: a cycloaliphatic monofunctional (meth)acrylate, a tetrahydrofurfuryl methacrylate, a 2-phenoxyethyl methacrylate, a butyl methacrylate, a benzyl methacrylate, an n-propylmethacrylate, a tertiary butyl acrylate, or at least one combination thereof,
wherein the group excludes isobornyl (meth)acrylate, and
wherein a cured homopolymer of the at least one monofunctional (meth)acrylate monomer has a Tg of 30 degrees Celsius (° C.) or greater, at least 40, 50, 60, 70, 80, or 90° C.; and
at least one urethane (meth)acrylate comprising polymerized units of an aliphatic polycarbonate diol.
