Abstract:
1. An alkali soluble polymer comprising a first and a second type of repeating units, each represented by Formula 1: where X is selected from (CH 2 )p, oxygen, sulfur, or NR″, p is equal to 1 or 2, R″ is C 1 to C 3 alkyl; m is an integer from 0 to 5, and each occurrence of R 1 , R 2 , R 3 and R 4 is independently a hydrogen, a linear or branched (C 1 to C 25 ) hydrocarbyl. a linear or branched (C 1 to C 25 ) halohydrocarbyl, a linear or branched (C 1 to C 25 ) perhalocarbyl, or one of —(CH 2 ) n —C(OH)—(CF 3 ) 2 , —(CH 2 ) n —N(H)—S(O) 2 —CF 3 , —(CH 2 ) n —C(O)—(OH), —(CH 2 ) n —C(O)—R 31 —(CH 2 ) n —O—C(O)—R 32 , —(CH 2 ) n —O—R 32 , and —(CH 2 ) n —O—CHR 33 —CHR 33 —R 41 , where n is an integer from 0 to 8, R 31 is one of a mono- or multi-functional phenol of Formula AA where A is optional and if present an oxygen, R 5, R 6 , R 7 , R 8, and R 9 independently represent hydrogen a linear or branched (C 1 to C 25 ) alkyl, a linear or branched (C 1 to C 25 ) halohydrocarbyl. a linear or branched ((C 1 to C 25 ) hydrocarbyl; and —(CH 2 ) n —O—R * , where n is an integer from 0 to 25, R * is H or a linear or branched hydrocarbyl or a halohydrocarbyl, with the proviso that for a mono-functional phenol only one of R 5 to R 9 is —OH and for a multi-functional phenol more than one of R 5 to R 9 is —OH an amino-phenol of Formula BB, where in Formula BB, R 5 , R 6 , R 7 ,R 8 , and R 9 are as defined for Formula AA with the proviso that at least one of R 5 or R 9 is —OH; —O—(CH 2 ) m —C(O)—OH where m is an integer born 1 to 5,—O—R 33 —C(OH)—(CF 3 ) n a where R 33 a liner or branched C 1 to C 5 alkyl, or —O—(CHR 40 —CHR 41 —O) m —R 42 where one of R 40 and R 41 is H and the other a C 1 to C 3 alkyl or both of R 40 and R 41 are H; and R 42 is R 32 as defined below or —C(O)—R 32 ; R 32 is one of a mono- or multi-functional phenol of Formula AA where A is not present, —(CH 2 ) m —C(O)—OH, R 33 —C(OH)—(CF 3 ) 2 ; with the proviso that for the first type of repeating unit within the polymer backbone, at least one of R
