RHEOLOGY OF 1,2- DICHLOROETHYL BENZENE / SKEPT-60 MIXTURES

Rheology was studied by obtaining binary mixtures based on 1,2-dichloroethyl benzene, taken as a polyfunctional alkylaromatic compound, and SKEPT-60 ethylene-propylene-diene (EPDM) elastomer as a high molecular compound. It has been found that the functional compound embedded in the elastomer can act in different ways depending on the amount and conditions in which it is incorporated. By adding 1,2-dichloroethyl benzene, the plasticization and construction of ethylene-propylene-diene elastomer can be carried out under the influence of different temperatures and loads. A two-roll mill was used to add 1,2 – dichloroethyl benzene to the polymer matrix. Double mixtures were obtained by the gradual addition of 1,2-dichloroethyl benzene to the elastomer in the temperature range of 30 – 50o C. The flow properties and rheology of the alloys of the binary mixtures obtained were investigated. The effects of processing conditions and 1,2-dichloroethyl benzene were determined by examining rheology. The rheology study allows to determine the optimal processing conditions, which is important for determining the method of obtaining higher quality mixtures. The effect of a functional compound such as 1,2- dichloroethyl benzene on SKEPT-60 was found to be significantly dependent on the applied voltage and temperature conditions.
