Abstract

In the present study, the effect of elastomer ratios in solution-based mixtures on the formation of the phase structure and properties of compositions based on butyl rubber, chlorobutyl rubber, and ethylene-propylene-diene rubber was investigated. This work determined the influence of the elastomer ratios in uncured blends and their impact on the patterns of phase structure formation in multicomponent polymer systems, alterations in molecular mobility, and their influence on ozone resistance. Attenuated total reflectance – Fourier transform infrared spectroscopy was employed to analyze the chemical structure of the polymer surfaces. The influence of blend ratio (mass percentage ratios of 100/0, 80/20, 60/40, 50/50, 40/60, 20/80, and 0/100) on the phase structure and surface ozone oxidation was studied. The green strengths of the blends of ethylene-propylene-diene rubber and butyl/chlorobutyl rubbers were studied over a wide range of blend ratios. [ABSTRACT FROM AUTHOR]

Abstract

The paper is devoted to the novel solution for the technology of chlorination butyl rubber – mechanochemical halide modification, as a more efficient way to obtain halogenated elastomers with a wide range of halogen content (from 3 to 15 %). The vulcanizing characteristics of elastomeric compounds based on the chlorinated butyl rubber as well as the production conditions of vulcanization process have been studied by the methods of differential scanning calorimetry and dynamic mechanical rheometry. The performed investigation revealed the optimum content of the vulcanizing agent (6 wt%) and accelerator (2 wt%) for chlorinated butyl rubbers compositions. The preferable vulcanization temperature of 150±5°C for rubbers under investigation regardless of chlorine content in a sample has been determined. The effectiveness of the process of vulcanization studies by combination of differential scanning calorimetry and dynamic mechanical rheometry methods with the purpose of comprehensive assessment of the rubber compositions vulcanization characteristics has been shown.
