1results about How to "Reduce volume shrinkage" patented technology

This invention relates to a polymerizable disulfide, its preparation method, and its uses, belonging to the fields of polymer chemistry and photopolymerization. It is proposed based on the significant volume shrinkage inherent in LED free radical photopolymerization. The beneficial effects of this invention are that the disclosed polymerizable disulfide compound can reduce the volume shrinkage of 405nm LED light-induced free radical photopolymerization, while also possessing initiation and polymerization properties. Furthermore, this disulfide can improve the heat resistance of photocurable materials, showing great application potential in the field of LED photopolymerization.
