The present disclosure provides a crosslinkable composition including a (meth)acrylate polymer and a visible light absorbing compound. Two percent or less of the carbon-carbon bonds in the crosslinkable composition are double bonds. The composition allows for inclusion of one or more materials degradable by ultraviolet radiation and/or stabilized against ultraviolet radiation. Methods for making a crosslinked composition is also provided. One method includes obtaining a crosslinkable composition and subjecting the crosslinkable composition to radiation having a wavelength of 400 nm or greater. Another method includes subjecting a crosslinkable composition to first and second radiations that are different from each other.
本公开提供了一种可交联组合物,包括一种(甲基)丙烯酸酯聚合物和一种可见光吸收化合物。可交联组合物中百分之二或更少的碳-碳键为双键。该组合物允许加入一种或多种可被紫外线辐射降解和/或抗紫外线辐射稳定的材料。还提供了制造交联组合物的方法。一种方法包括获得可交联组合物,并将可交联组合物置于波长为 400 纳米或更大的辐射中。另一种方法包括将可交联组合物置于彼此不同的第一和第二辐射中。
