Scope
Main technical content: This document specifies the method for determining the content of phenyl and vinyl groups in phenyl silicone rubber raw materials by nuclear magnetic resonance hydrogen spectroscopy. This document is applicable to high-molecular-weight polysiloxane raw materials composed of dimethylsiloxane chains - Me2SiO-, diphenylsiloxane chains - Ph2SiO-, or methylphenylsiloxane chains - MePhSiO- and a small amount of methylvinylsiloxane chains - MeViSiO-. This document is suitable for determining the content of phenyl groups in phenyl silicone rubber raw materials that are not less than 3% and the content of vinyl groups that are not less than 0.1%. Note: For samples with phenyl and vinyl content outside the above range, they can also be tested by this method after reasonable verification.
