Abstract

The invention belongs to the field of organosilicon materials, and discloses preparation and application of a polycyclic siloxane polyether copolymer. A structural formula of the polycyclic siloxane polyether copolymer is shown in the specification, wherein B refers to a substituent group of a polyether-contained chain segment, and A refers to a linking group of a polysiloxane-contained chain segment. The polycyclic siloxane polyether copolymer can be obtained by subjecting 1, 3, 5, 7-tetramethyl cyclotetrasiloxane, an allyl polyether compound and alpha, omega-divinyl-terminated polysiloxane to hydrosilylation reaction. In a structure of the polycyclic siloxane polyether copolymer, multiple polycyclic polyether-based siloxane oligomers are linked, and according to the structure, hydrophilia, easily-emulsifying property and antistatic property of the polycyclic siloxane polyether copolymer can be regulated and controlled, so that the polycyclic siloxane polyether copolymer can be used for multiple fields including daily bathing, skin caring and the like.

Description

technical field [0001] The invention belongs to the field of organosilicon materials, and in particular relates to the preparation and application of a polycyclic polyether siloxane copolymer. Background technique [0002] Polymers with water-soluble polyoxyethylene polyoxypropylene ether groups and polysiloxane chain segments connected at the same time in the molecular structure have good water solubility, hygroscopic and antistatic properties or waxy feeling endowed by polyether groups. It also has the unique soft moist feeling or lubricating performance of polysiloxane chain segment, so it is widely used in daily chemical bath products, skin care products, yarn lubricants, leather softeners, water-soluble antistatic silicone wax, etc. [0003] Hydrosilylation reaction is a common method for synthesizing polyether-based siloxane compounds, which can be seen in invention patents CN101959938, CN101472979, CN101389693, CN 103492463A, CN 102964602, CN 104204101A, etc. But as ...
