The swelling of castor oil polyurethane/polymethyl methacrylate crosslinked copolymers in a number of solvents has been studied. It is found that the swelling behavior is in relation with the presence of the continuous phase in the crosslinked copolymers and the binary diffusion coefficients are able to reflect the phase inversion of the copolymers.
- castor oil polyurethane,
- polymethyl metharylate,
- crosslinked copolymer,
- swe-lling,
- phase inversion
