WebApr 18, 2024 · The solubility of the copolymers increased with higher content of Si–H in the polymer backbone. The exothermic DSC peak due to cross-linking was observed at 220–260 °C. The weight loss at 5% in nitrogen was 629–686 °C and the char yield at 1000 °C was 88–91%, reflecting increasing stability with higher Si–H content. WebThe term polymer is used to describe compounds with relatively large molecular weights formed by linking together many small monomers. Polyethylene, for example, is formed …
