ABSTRACT:
A process for producing porous, low molecular weight vinyl polymers and copolymers via suspension polymerization in the presence of a dual function porosifier/low molecular weight modifier is disclosed. The process is especially advantageous in that it can be run at a wide variety of temperatures to obtain super porous, low molecular weight resins. Novel super porous, low molecular weight resins are also disclosed.
