Industrial Applications of 88820-71-7
| Industry | Application | Process |
|---|---|---|
| Silicone Synthesis | Modification or synthesis of silicone rubber and silicone resins | Used as a bifunctional silane monomer bearing vinyl and chloropropyl groups, incorporated into polymer backbones or side chains via condensation or addition reactions |
| Silicone Rubber/Adhesives | Coupling agent/crosslinker | In surface treatment of silica filler, the chloropropyl group reacts with surface hydroxyl groups while the vinyl group participates in crosslinking of the rubber matrix, enhancing mechanical strength and adhesion |
| Fine Chemicals | Organic synthesis intermediate | Vinyl group undergoes hydrosilylation; chloropropyl group undergoes nucleophilic substitution to synthesize structurally complex silane derivatives |
