The hydroxyl NMR frequencies for t-butanol, phenol, and methanol have been measured as functions of concentration in carbon tetrachloride solution. The curves obtained were found to fit well to theoretical curves calculated for monomer-trimer equilibrium for t-butanol and phenol with K3=5.60 l2/M2 and 4.78 l2/M2, respectively and a monomer-tetramer curve with K4=28.4 l3/M3 for methanol. The data of Becker et al.1 on the ethanol-carbon tetrachloride system have been fitted to theoretical curves for monomer-trimer K3=5.19 l2/M2 and monomer-tetramer K4=44.9 l3/M3.

The various proposed structures for polymers derived from benzyl type compounds have been discussed and the likelihood of these structures considered in the light of a study of their preparation and properties. Both the para substituted structure of Shriner and Berger and the pendant structure of Henne and Leicester were rejected chiefly on the basis of physical properties, degradation behavior, and x‐ray and infrared evidence. Flory's randomly branched structure also fails to account for the degradation behavior and the infrared spectrum. A new configuration which is a nonrandomly substituted, highly branched molecule is advanced. This structure contains predominantly two types of benzene rings, i.e., a relatively small number of highly substituted rings and a considerably larger number of monosubstituted benzenes existing in the form of pendant benzyl groups.
