Abstract
It is an object of the present invention to provide a resin composition whose birefringence has been controlled. The object can be attained by a resin composition composed essentially of a resin (A) containing glutarimide units and acrylic ester units and a resin (B) containing glutarimide units, acrylic ester units, and aromatic vinyl units. The resin composition of the present invention is easy to manufacture, inexpensive, excellent in terms of transparency and heat resistance, and easily controllable in terms of orientation birefringence. Further, the resin composition of the present invention can be developed to be applied to an optical molding product of which transparency and heat resistance are required.
