A copolymer comprising (a) a monomer having a C7 to C21 perfluoralkyl or perfluoralkenyl group at one end of the molecule and an ethylenically unsaturated group at the other end of the molecule, and (b( a monomer having a photosensitive group, e.g. an azidobenzoyloxy group, cinnamoyloxy group, benzoylphenyl group or a,#- unsaturated ketone group. The copolymer has an excellent photosensitivity and excellent water and oil repellent properties, and is useful for various purposes, e.g. as a photosensitive material for dry offset printing plate or resist and as a photo-curable, water and oil repelling coating material.
一种共聚物,包括(a)分子一端为 C7 至 C21
全氟烷基或
全氟烯基,分子另一端为
乙烯基不饱和基团的单体,以及(b)具有感光基团(如
叠氮苯甲酰氧基、肉桂酰氧基、苯甲酰苯基或 a,#-不饱和酮基)的单体。这种共聚物具有极佳的感光性和优异的防
水防油性能,可用于多种用途,例如用作干胶印印版或抗蚀剂的感光材料,以及用作光固化防
水防油涂层材料。
