Peculiarities of the production of materials based on polysulfide oligomer-polymerizable compound compositions cured in the presence of manganese oxide

The effect of the physicochemical structure of polymerizable compounds on the curing process, structure, and properties of the materials based on liquid thiocols is studied. It is shown that the introduction of oligoacrylates in the amount of 2.5–10 vol % increases the extent of cross-linking, conte...

Description
Summary:The effect of the physicochemical structure of polymerizable compounds on the curing process, structure, and properties of the materials based on liquid thiocols is studied. It is shown that the introduction of oligoacrylates in the amount of 2.5–10 vol % increases the extent of cross-linking, content of gel fraction, and stress-strain parameters of elastomers and leads to smoothing of the material surface microrelief and decrease of the amount of micropores, which facilitates reduction in swelling ofelastomers in aggressive media.
