Аннотация:Colorless transparent vulcanizates of silicone elastomers were prepared by mixing thecomponents in a common solvent followed by solvent removal. We studied the correlation betweenthe mechanical behavior of polydimethylsiloxane (PDMS)-rubber compositions prepared using MQ(mono-(M) and tetra-(Q) functional siloxane) copolymers with different ratios of M and Q parts as amolecular filler. The composition and molecular structure of the original rubber, MQ copolymers,and carboxyl-containing PDMS oligomers were also investigated. The simplicity of the preparationof the compositions, high strength and elongation at break, and their variability within a wide rangeallows us to consider silicone elastomers as a promising alternative to silicone materials prepared bytraditional methods.
