Abstract

The invention discloses a (meth)acrylic acid ester monomer without bisphenol A structure and low polymerization volume shrinkage, its preparation method and application. The (meth)acrylate macromonomer without bisphenol A structure prepared by the invention can be used as an organic monomer component of dental restorative materials. The macromonomer has the characteristics of large molecular weight, large molecular volume, and no bisphenol A structure. Therefore, the macromonomer has a small polymerization volume shrinkage during polymerization, and can reduce the presence of dental materials with a bisphenol A structure on the human body. potential hazards.

Description

technical field

[0001] The invention relates to a series of monomers that can be used as photoinitiated polymerization systems, in particular to a series of (meth)acrylic ester monomers without bisphenol A structure and low polymerization volume shrinkage, as well as its preparation method and application. Background technique

[0002] At the end of the 19th century, American dentist Miller first proposed the bacterial mechanism of dental caries in his book Microorganisms in the Human Mouth, that is, bacteria ferment sugar to produce acid, which leads to demineralization of tooth enamel and caries. After dental caries occurs, the tooth itself cannot repair itself, and the diseased part can only be removed through dental surgery, and then filled with certain restoration materials. Due to the wide application range, convenient use, low price, and large modification space of composite resin-based restoration materials; at the same time, because composite resin can be directly b...
