Investigating the influence of polysulphide oligomers in oligoacrylate-based composites on the structure formation and the properties of photocurable materials

摘要

An investigation was made of the influence of polysulphide oligomers on the curing process and the structure and properties of materials based on photocurable composites. Itwas shown thatthe use of a polysulphide oligomer lowers the shrinkage and internal stresses in materials. It was established that the introduction of thiokol polysulphide into photocurable composites makes it possible to increase the elastic strength and deformation properties and the corrosion resistance of the materials.
