Patent ID: 8883897

Claim:
A composition of functional norbornanyl ester derivatives represented by the general Formula-1 wherein R 1 is a hydrogen atom, a methyl, or a hydroxymethyl group and R 2 , R 3 , and R 4 are the same or different from each other and are independently selected from the group consisting of hydrogen; halogen; hydroxyl; acid (—C(O)OH); ester (—C(O)OR a ); formate (—OC(O)H); acid halide (—C(O)Z); aldehyde (—C(O)H); ketone (—C(O)R a ); nitro (—NO 2 ); carboxamide (—C(O)NR a R b ); amine (—NR a R b ); silicone (—SiR a R b R c ); cyano (—CN); isocyanate (—NCO); alkoxy (—OR a ); phosphonate (—P(O)R a R b ); unsubstituted or substituted C 1 -C 100 alkyl group; unsubstituted or substituted C 2 -C 100 alkenyl group; unsubstituted or substituted C 2 -C 100 alkynyl group; unsubstituted or substituted C 3 -C 100 cycloalkyl group; unsubstituted or substituted C 6 -C 100 aryl group; provided that when it is substituted with one or more substituent groups, the substituent group may be carboxyl, hydroxyl, thiol, halogen, ester, amine, amide, imide, isocyanate, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, aryl, haloaryl, aralkyl, haloaralkyl, alkoxy, haloalkoxy, halocarbonyloxy, aryloxy, haloaryloxy, silyl, siloxy, glycidoxy, heterocyclo, carbonate, carboxylate, or quaternary ammonium; with the proviso that at least one of R 2 , R 3 , and R 4 is a polar functional group containing at least one atom selected from the group consisting of oxygen, nitrogen, phosphorus, sulfur, silicon and boron; R 2 , R 3 and R 4 may be an acid anhydride group (—C(O)—O—C(O)—) or a imide group (—C(O)—NR d —C(O)—) formed by being bonded to each other when they are the functional groups; R 5 is a substituted alkane, alkene, or cycloaliphatic group wherein at least one substituent group is a carboxyl or ester group; X represents oxygen, CH 2 , or CH 2 —CH 2 ; k is an integer of 0 to 100; l is an integer 0 to 1; m and n both represent an integer 0-5; Y is a bridge member selected from the group consisting of (—C(O)O—), (—R 6 —), (—R 7 C(O)O—), (—C(O)OR 7 O—), (—C(O)OR 7 OC(O)—), (—O—), (—OR 7 O—), (—R 7 OC(O)OR 8 —), (—R 7 C(O)OR 8 —), and (—R 7 C(O)R 8 —); R a , R b and R c are independently hydrocarbyl or substituted hydrocarbyl; R d is a hydrocarbyl group substituted with hydroxyl, alkoxy, alkenyl, amine, amide or imide group; Z is a halogen atom; R 6 , R 7 , R 8 are divalent organic groups and may be substituted or unsubstituted alkanes, alkenes, or cycloaliphatic groups.
