Document Type and Number:
WIPO Patent Application WO/2022/196720
Kind Code:
A1
Abstract:
[Problem] A purpose of the present invention is to provide a siloxane compound having an amide bond and a (meth)acrylate group. Another purpose of the present invention is to provide a method for producing a siloxane compound that has a purity useful as a medical material. [Solution] A siloxane compound represented by formula (1). [Chem. 1] (In the formula, R1 represents a hydrogen atom or a methyl group, R2 represents a hydrogen atom or a monovalent hydrocarbon group having 1-6 carbon atoms, L1 represents a divalent hydrocarbon group having 1-5 carbon atoms, L2 represents a divalent hydrocarbon group having 2-10 carbon atoms and optionally including an ether bond, and A represents a polysiloxane unit represented by formula (2) or (3)). ) [Chem. 2] [Chem. 3] (In the formulae, n represents an integer of 1-100, 'a' represents an integer of 0-10, b represents an integer of 0-10, c represents an integer of 0-10, but a+b+c equals 2 or more, R and R3 each independently represent a monovalent hydrocarbon group having 1-10 carbon atoms, and a site indicated by ** is a binding site with respect to L2 in formula (1)).
