摘要
Abstract
In this paper,molecular weight,distribution of molecular weight and degradation temprature of Russia and domestic liquid polysulfide rubber were analysized by GPC and TG.Their polysulfide character peaks were affirmed by FTIR.Two polysulfide sealants were prepared using the liquid polysulfide rubber and their mechanics properties of normal temperature,heat aging and 3# jet oil aging were tested.The results showed that number molecular weight and viscosity of Russia polysulfide rubber was less than domestic polysulfide rubber,but the degradation temprature of it was higer.The mechanics properties of heat aging of Russia polysulfide sealant was better than domestic polysulfide sealant,but the mechanics properties of 3# jet oil aging of it was worse.关键词
