Conclusions
-
1.
Diamine added to a PVC mixture treated for 15 min on rollers promotes a strength, gain due to a knitting together of structural elements using macroradicals mat form during mechanical destruction.
-
2.
An increase in treatment temperature above 160°C results in deactivation of the diamine by retaining it in the hydrochloride form of hydrochloric acid liberated in the process of thermal destruction; the latter is predominant under these conditions.
-
3.
The maximum mechanical strength of articles formed from PVC and worked on rollers for 15 min occurs with an additive of 4.25% diamine and at a temperature of 170°C.
