Abstract
Stereo-regular polymers are produced by forming a moving stream of gaseous monomer having an electric dipole moment, irradiating the monomer with monochromatic light of a wavelength suitable for activating it, and orientating the activated monomer in an electric field. The activated, orientated monomer then polymerizes to form a stereo-regular polymer. Alternatively, a monomer of the general formula ##STR1## can be used, where at least one of the R groups, the resonating R group, forms an electric dipole moment with the remainder of the monomer. The monomer is then irradiated with a monochromatic light beam having a frequency which resonates with a harmonic frequency resulting from the bond between the resonating R group and the remainder of the monomer. Activation of that particular bond on that particular type of monomer results in a stereo-regular polymer. For best results, however, the two methods are combined.
