A study of the mechanism of interaction between polysulphide oligomers and methyl methacrylate

The effect of plasticizers on properties of epoxy-thiokol adhesive compositions

“…Thus, the smallest increase in τ sh is observed for MGF 9, the introduction of which provides the maximum increase in σ t . One possible reason for such influence of this plasticizer is the chemical interaction between thiokol and methacrylic acid that is part of MGF 9 [10][11][12]. Additional con firmation of this interaction can be found in the results of measuring the dynamic elastic modulus in the high elasticity states of the samples (Fig.…”

Investigating the Structure and Properties of Materials Based on Composites of a Polysulphide Oligomer and a Polymerising Compound

“…In the traditional vulcanisation of PSOs, disulphide bonds are formed by the mercapto groups, which are prone to breakdown on exposure to corrosive media. Known methods of thiokol modification by derivatives of methacrylic acid [6][7][8][9] are ineffective for the production of corrosion-resistant materials. We assumed that increase in chemical resistance can be achieved by the interaction of polymerising compounds and the thiokol oligomer not only by terminal mercapto groups but also by the disulphide bonds of the PSO, which may occur at high temperatures or in the presence of peroxide compounds at room and elevated temperatures.…”
