✦ Synopsis
The flowability and thermal behavior of waxy solutions with and without an ethylenevinyl acetate copolymer (EVA) have been studied. The drastic changings of pour point depression (ATpp) and the crystallization in four waxy solutions were observed. These changes were linear with the U-interaction parameters between EVA and wax in different solvents, suggesting that the efficiency of EVA pour point depressant depends on its compatibility with wax, which is affected by solvent.

Measurements were made of the value of the lumped kinetic constant k p /k t 0.5 of vinyl acetate in different solvents and with different initiators. This quantity was evaluated using the well-known conversion vs. time approach in dilute solutions using both azo-bis-isobutyronitrile and benzoyl pero
