ChEBI: A polymer composed of repeating 1,1-dimethylethylene units. | [Preparation]
Silicone rubbers are prepared as follows:
Other groups may replace the methyl groups. Silicone rubbers have excellent ozone and weathering resistance, good electrical properties, and good adhesion to metal. | [Solubility in organics]
