MODIFIED VINYLSILANE, AND PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2023/130551

A1

A modified vinylsilane, and a preparation method therefor and the use thereof. The modified vinylsilane is obtained by grafting an oily group, a silicone oil group, or a ring-opening group of a dimethyl siloxane ring body onto vinylsilane. The resulting modified vinylsilane has an improved oiliness, a relatively low viscosity and an enhanced dispersity; and when the modified vinylsilane is used as a coupling agent for an organic and/or inorganic powder, the modified powder has a good dispersity and can be uniformly and stably grafted onto the organic and/or inorganic powder to improve the stability of the modified material. The modified vinylsilane is prepared by subjecting vinylsilane and a modifying reagent to a rearrangement reaction under the action of a catalyst, and the modifying reagent has a high oiliness and a high dispersity, and can enhance the dispersing capacity of the modified vinylsilane, improve the grafting capacity of the modified vinylsilane in the organic and/or inorganic powder, and increase the binding force between the modified vinylsilane and the organic and/or inorganic powder when the modified vinylsilane is used as a coupling agent.
