Monomer compound (I) is new. Monomer compound (I) of formula (R 1>-O-CO-C(=CHR)-Y 1>-O-Q(AH) n) is new. Either A : -CO 2->or SO 3->; or A+H +>AH; Q : 1-12C alkylene, 4-12C alkylene (interrupted by -O-,=N- or -S) or 6-15C arylene (optionally substituted by 1-4C alkyl, 1-4C alkoxy or halo), where arylene and aryl groups further carries acid groups A; Y 1>1-12C alkylene or 4-12C alkylene (interrupted by -O-, =N- or -S); R : CH 3or H; R 1>1-6C alkylene; and n : 1-3. Independent claims are also included for: (1) preparation of (I); (2) a composition comprising (I), a polymerizable monomer, optionally one/more initiator, and a filler, pigment and/or stabilizer; and (3) a dental material (II) comprising (I). |
