The preparation of ethyl rubber is a fine chemical process that requires extremely high process control. The core synthesis route usually adopts the co hydrolysis and condensation reaction of dimethyl dichlorosilane and diethyl dichlorosilane, or the ring opening copolymerization of specific siloxanes with hexaethylcyclotriosiloxane under the action of alkaline catalysts.

Throughout the entire polymerization process, conditions such as reaction temperature, pressure, type and dosage of catalyst must be precisely controlled to ensure that the ethyl group can be evenly distributed in the polymer molecular chain, thereby obtaining an ideal and stable molecular structure. Any small process fluctuations can lead to significant differences in the performance of the final product.

Due to inherent deficiencies in heat resistance of pure ethyl rubber, various methods are often used in modern materials science to modify it. A common method is to introduce heat-resistant fillers such as graphene or oxidized graphene into the formula, which can effectively reduce the loss rate of tensile strength of the material under high temperature conditions and slow down the thermal aging process.

Another more comprehensive modification strategy is to introduce both ethyl and phenyl groups into the main chain of silicone rubber to prepare phenylethyl silicone rubber. This copolymer not only inherits the excellent low temperature resistance and damping properties of ethyl rubber, but also greatly improves the thermal stability and radiation resistance of the material by utilizing the rigid structure of the benzene ring, thus meeting more demanding industrial application requirements.
