The

C T

of --CH

side group in PPU/P （St-co-AA）

AB-crosslinked polymers （i. e.ABCP） was studied by using high resolution solid state NMR. The rotation motion of --CH

sidegroup in PPU was analyzed by means of the average spectral density functions of internal rota-tion. The results showed that the rotation of the --CH

side group is related closely to the com-patibility between the two components. The compatibility was studied by analyzing the protonspin-lattice relaxation in rotating frame

spin-spin relaxation and spin-diffusion. The resultsshowed that the hydrogen bonds between the components play a major role in determining thecompatibility. Through spin diffusion studying

the soft phase domain size was calculated. Bystudying proton spin-spin relaxation

the content of each component in each phase and that ofeach phase in the samples can be obtained. The result shows that the content of interphase is related closely to the compatibility.
