Abstract:
A copolymer composition comprising polycyclic and acrylic repeating units of the formulae: ##STR21##wherein R.sup.1 to R.sup.4 independently represent a radical selected from a group consisting of --(CH.sub.2).sub.n --C(O)OR.sup.5, --(CH.sub.2).sub.n --OR.sup.5, --(CH.sub.2).sub.n --OC(O)R.sup.5, --(CH.sub.2).sub.n, --C(O)R.sup.5 --(CH.sub.2).sub.n --OC(O)OR.sup.5, and --(CH.sub.2).sub.n C(O)OR.sup.6, wherein m represents an integer from 0 to 5, n independently represents an integer from 0 to 10; R.sup.5 independently represents hydrogen, linear or branched (C.sub.1 -C.sub.10) alkyl, linear or branched, (C.sub.2 -C.sub.10) alkenyl, linear or branched (C.sub.2 -C.sub.10) alkynyl, (C.sub.5 -C.sub.12) cycloalkyl, (C.sub.6 -C.sub.14) aryl, (C.sub.7 -C.sub.24) aralkyl, and halogenated substituents thereof; R.sup.6 represents an acid labile moiety; R.sup.8 is hydrogen or methyl; or R.sup.9 independently is selected from a group consisting of hydrogen, an acid labile group, linear and branched (C.sub.1 -C.sub.10) alkyl, linear and branched, (C.sub.2 -C.sub.10) alkenyl, linear and branched (C.sub.2 -C.sub.10) alkynyl, (C.sub.5 -C.sub.12) cycloalkyl, (C.sub.6 -C.sub.14) aryl, (C.sub.7 -C.sub.24) aralkyl; and halogenated substituents thereof.
