Abstract

The present invention discloses a methacrylate macromonomer containing a fluorine structure but not containing a bisphenol A structure, preparation method therefor and application thereof. The prepared methacrylate macromonomer containing fluorine structure not containing bisphenol A structure can be used as an organic monomer component of a dental restorative material. The macromonomer has the advantages of large molecular weight, large molecular volume, not containing a bisphenol A structure and containing a fluorine structure. Therefore, when the macromonomer is polymerized, the polymerization volume shrinkage is small and a polymerization product has a good mechanical property.

Description

technical field

[0001] The invention relates to a macromonomer that can be used as a photoinitiated polymerization system and its preparation method and application, in particular to a methacrylate macromonomer with a fluorine-containing structure and no bisphenol A structure, and its preparation method and application. Background technique

[0002] Dental caries and periodontal pulp disease are frequently-occurring and common diseases in clinical oral cavity, among which dental caries is listed by the World Health Organization as one of the three major human diseases, according to the "Third National Oral Health Epidemiological Survey Report" shows In my country, the caries rate of deciduous teeth and permanent teeth is as high as 66% and 28% respectively. If it is not treated in time, it will continue to develop into periapical pulp disease, and even cause alveolar bone and jaw inflammation, seriously affecting patients. quality of life. Therefore, it is necessary to carry ...
