Abstract
Abstract This invention relates to a polymeric vehicle comprising a modified polymer containing covalently bonded mesogenic groups. The modified polymer may be used as the sole component of the polymeric vehicle for a coating to which may be added solvents and known additives to provide a formulated coating. The polymeric vehicle may further include other modified or unmodified polymers and cross-linking resins. The polymeric vehicle provides a coating binder and coating film of high hardness, flexibility and impact resistance.
