Description

technical field [0001] The invention relates to the technical field of photosensitive polymer materials, in particular to a hyperbranched acrylate based on maleic anhydride as a photopolymerizable monomer. Background technique [0002] Photopolymerization (also known as photocuring) technology is the process of using light (ultraviolet light or visible light) to trigger the rapid transformation of chemically reactive liquid substances into solid substances. It is a new green technology that came out in the 1960s. In 1946, Inmont Corporation of the United States published the patent for unsaturated polyester / styrene UV curing ink for the first time. By the end of the 1980s, UV curing technology had maintained an average annual growth rate of more than 15%. Since the mid-1990s, it has been growing rapidly at an annual rate of nearly 10%, and there is still a growing trend in some fields. Light curing technology has the characteristics of high efficiency, wide adaptability, ec...
