FIELD: chemistry.
SUBSTANCE: invention relates to rubber compositions. The composition contains diene-based rubber and one polyether or polyglycol ether based on cycloaliphatic epoxide. The composition can contain filler and a vulcanising agent. Another version of the composition contains diene-based rubber and one polyether or polyglycol ether based on cycloaliphatic epoxide and one filling oil. The filling oil is selected from a group consisting of aromatic oil, aliphatic oil, naphthene oil and mixtures thereof.
EFFECT: invention provides higher rate of vulcanisation, improved relative elongation and a higher modulus of elasticity with 300% elongation, improved dynamic mechanical properties.
