304 III. CHEMISTRY OF NEUTRAL FATS 



groups in the polymer are increased from 10 to 20; on the other hand, when 

 p is raised from 0.99 to 0.999, the number of groups in the molecular com- 

 plex is augmented from 100 to 1000. 



The formation of polymers with the triglycerides is believed by Brad- 

 }gy555,556 ajjd Carothers^" to be the result of actual valence cross ties between 

 the molecules, although the existence of covalence forces is not entirely 

 precluded. The triglyceride configuration appears to be particularly ap- 

 propriate, because of space relationships, for the formation of intermolecu- 

 lar combinations of exceeding complexity. For this reason the unsatu- 

 rated triglycerides occupy such an important position in the paint industry, 

 in the production of insoluble dry films. In addition to the papers of 

 Bradley^^*'^^^ a very excellent detailed discussion of the phenomenon of 

 polymerization and condensation is included in a series of reports before 

 the Faraday Society.*"-^^^
