Title:
SINGLY TERMINATED ORGANOSILOXANE MACROMONOMER, SILICONE HYDROGEL, CONTACT LENS AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/141795
Kind Code:
A1
Abstract:
Disclosed is a singly terminated organosiloxane macromonomer, which intermixes effectively with various hydrophilic monomers when there is no solvent for dissolution, and can be used for preparing a silicone hydrogel material with high oxygen permeability and high hydrophilicity. Further provided is a silicone hydrogel, which is prepared by means of a polymerization reaction of the singly terminated organosiloxane macromonomer and the following components: 5-60 parts of the singly terminated organosiloxane macromonomer, 0-30 parts of a micromolecular silicon monomer, 10-70 parts of a hydrophilic monomer, and an initiator and a cross-linking agent. The silicone hydrogel has good hydrophilic performance, good light transmittance performance and high oxygen permeability. In addition, further provided is a contact lens, which is made of the silicone hydrogel material, and has the advantages of good oxygen permeability, good light transmittance performance, strong hydrophilicity, being comfortable for wearing, etc.
