Notes:
Stereospecific polymerization of deuterated methyl methacrylates, CH2=C(CH3)-COOCD3, CD2=C(CD3)COOCH3, and CD2=C(CD3)COOCD3, which were prepared by the acetone-cyanohydrin method, were carried out. From the polarized infrared study of polymethyl methacrylate and its deuterated analogue, the spectra of stereo-regular polymethyl methacrylates were tentatively assigned in the 4000-400 cm.-1 region. The isotactic polymers are easily crystallized and show intensity variations of bands. These bands originate mainly from the deformation vibrations of the α-CH3 group, the stretching vibrations of the C—C—O side chain, and the skeletal stretching vibration coupled with CH2 rocking vibration.
