PHASE STABILITY OF FROST-RESISTANT BINDERS BASED ON PROPYLENE OXIDE RUBBER
Relaxation and phase transitions of frost-resistant plasticizers were studied: transformer oil, dioctyl adipate, dioctyl terephthalate, dibutyl sebacate, dibutyl phthalate. The thermodynamic compatibility of synthetic propylene oxide rubber with frost-resistant plasticizers has been studied. The phase stability of model binders with 80% plasticizer at negative temperatures was studied and their glass transition temperature was determined. For binders based on propylene oxide rubber and plasticizers of dioctyl adipate, dibutyl phthalate, and dioctyl terephthalate, there are no signs of phase decomposition at low temperatures
