Disclosed is a process which comprises reacting a polymer of the general formula ##STR1## wherein x is an integer of 0 or 1, A is one of several specified groups, such as ##STR2## B is one of several specified groups, such as ##STR3## or mixtures thereof, and n is an integer representing the number of repeating monomer units, with an acetyl halide and dimethoxymethane in the presence of a halogen-containing Lewis acid catalyst and methanol, thereby forming a haloalkylated polymer. In a specific embodiment, the haloalkylated polymer is then reacted further to replace at least some of the haloalkyl groups with photosensitivity-imparting groups. Also disclosed is a process for preparing a thermal ink jet printhead with the aforementioned polymer.
A process which comprises reacting a polymer of the formula ##STR121## wherein x is an integer of 0 or 1, A is ##STR122## or mixtures thereof, B is ##STR123## wherein v is an integer of from 1 to about 20, ##STR124## wherein z is an integer of from 2 to about 20, ##STR125## wherein u is an integer of from 1 to about 20, ##STR126## wherein w is an integer of from 1 to about 20, ##STR127## or mixtures thereof, and n is an integer representing the number of repeating monomer units, with an acetyl halide and dimethoxymethane in the presence of a halogen-containing Lewis acid catalyst and methanol, thereby forming a haloalkylated polymer.
