A soluble UVA and/or UVB absorbing chromophore-comprising polymer useful for preparation of a sunscreen lotion has a multiplicity of repeating units where one or more of the repeating units includes at least one UVA and/or UVB absorbing chromophore. The repeating units are those formed from the ring-opening metathesis polymerization (ROMP) of a strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene, or where one or more sp

hybridized carbons of the strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene is replaced with a heteroatom. The UVA and/or UVB absorbing chromophore-comprising polymer can be formed from a UVA and/or UVB absorbing chromophore-comprising monomer, which can be homopolymerized or copolymerized by ROMP. Alternately, the UVA and/or UVB absorbing chromophore-comprising polymer can be formed by polymerization of monomers that can subsequently be substituted with UVA and/or UVB absorbing chromophores.
一种可溶于UVA和/或UVB的吸收色团的聚合物,用于制备防晒乳液,具有多个重复单元,其中一个或多个重复单元包括至少一个UVA和/或UVB吸收色团。这些重复单元是由环开放
金属卡宾聚合(ROMP)形成的,所述环为张力环烯烃,环烷二烯,双环烯烃或双环烷二烯,或其中一个或多个张力环烯烃,环烷二烯,双环烯烃或双环烷二烯的sp3杂化碳被替换为杂原子。该UVA和/或UVB吸收色团的聚合物可以由UVA和/或UVB吸收色团的单体形成,该单体可以通过ROMP进行同聚或共聚。或者,该UVA和/或UVB吸收色团的聚合物可以由可随后用UVA和/或UVB吸收色团进行取代的单体聚合而成。
