Abstract
Properties of some linear oligobenzyls corresponding to polybenzyl, poly(2,5‐dimethylbenzyl), and poly(2,3,5,6‐tetramethyl‐benzyl) systems are correlated to those of relative polymers. From infrared and x‐ray diffraction data, evidence is found that magnified image oligomers tend to assume the same crystal structure of the polymer as early as teh tetramer or pentamer stage. Syntheses of oligomers are described. Linear, crystalline polymers, necessary for comparison with oligomers, have been prepared and characterized. Polymerization conditions have been explored to some extent; relevant data are tabulated and discussed.
