A method of preparing a monomer comprises reacting a sultone of the formula (I):
wherein each R is independently F, C
1-10
alkyl, fluoro-substituted C
1-10
alkyl, C
1-10
cycloalkyl, or fluoro-substituted C
1-10
cycloalkyl, provided that at least one R is F; n is an integer of from 0 to 10, and m is an integer of 1 to 4+2n, with a nucleophile having a polymerizable group. Monomers, including a photoacid-generating monomer, may be prepared by this method.
一种制备单体的方法包括将公式(I)的磺酮与具有聚合基团的亲核试剂反应,其中每个R独立地为F、C1-10烷基、
氟取代的C1-10烷基、C1-10环烷基或
氟取代的C1-10环烷基,但至少一个R为F;n为0至10的整数,m为1至4+2n的整数。通过这种方法可以制备单体,包括光酸生成单体。
