Fund Project:

Poly(vinyl acetate)/poly(methacrylate) interpenetrating polymer networks(PVAc/PMA IPNs) and semi-IPNs were swollen in toluene under the thermodynamic condition of phase separation,or the PVAc component of the IPNs was alcoholyzed to decrease the compatibi-lity between two components.No phase separation was found in IPNs and semi-IPNs with high crosslink density of network I.It is indicated that the mutual entanglements between the two networks is permanent physical entanglements and the phase of the IPNs is stable.
- Poly(vinyl acetate)/poly(methaerylate) 1PNs,
- Permanent entanglement,
- Compatibility
