Abstract
A mixture of poly(2,3-dichloro-1-propyl acrylate) and poly(glycidyl methacrylate-co-ethyl acrylate), with the latter forming between 1 percent and 20 percent by weight, of the total polymer mixture, has been found to form an x-ray resist having adhesive and resolving properties superior to those of poly(2,3-dichloro-1-propyl acrylate) which is a good x-ray resist material. Superior properties of the mixture are attributed to the fact that the two polymers form a compatible polymer mixture which is a relatively rare and unpredictable event in polymer chemistry.
