A series of UV-cured AB crosslinked polymers (ABCP) based on vinyl-terminated polyethylene adipate polyurethane and methyl methacrylate were prepared. The dynamic mechanical properties
glass transition
morphology and crosslinking density of the AB crosslinked polymers were studied by using Rheovibron
TEM and equilibrium swelling. Two glass transition temperatures
Tg
corresponding to these of polyurethane and PMMA phases were observed and mic-rophase separation was eventually evident with TEM. The two Tgs were shifted inwardly in ABCP indicating that the chemical crosslinking between wo components increased the mutual miscibility. IPN with similar composition to ABCP have much larger phase domains than ABCP. Hydrogen bond influenced greatly the compatibility
morphology and dynamic mechanical pro-perties of ABCP.
