Abstract
The present invention provides a macroporous copolymer having large pores, typically in the range of 5,000-200,000 Å and a typical breaking weight of at least 175 g/bead. The macroporous copolymers can be made using an interpenetrating polymer network (IPN) techniques. These macroporous copolymers may also form macroporous resins. The present invention also provides methods of using the macroporous copolymers and resins.
