摘要：
Patent Summary: "Monomer-based dental materials with on-demand peel properties". The present invention relates to a dental restorative material comprising a thermolabile or photolabile polymerizable compound of formula I: [(z1) m-q1-x)] kt- [y-q2- (z2) n] 1 formula i, where t represents a thermolabile or photolabile group, z1 and z2 in each case independently represent a polymerizable group selected from vinyl groups, ch2 = cr1-co-o- and ch2 = cr1-co-nr2- or an adhesive group selected from –si (or) 3, -cooh, -o-po (oh) 2, -po (oh) 2, -so2oh and -sh, where at least one of z1 or z2 is a polymerizable group, q1 in each case independently is absent. or represents a linear or branched (m + 1) aliphatic C1-C20 radical which may be interrupted by -o-, -s-, -co-o-, -o-co-, -co-nr3-, - nr3-co-, -o-co-nr3-, -nr3-co-o- or -nr3-co-nr3-, q2 in each case independently is absent or represents a linear or branched aliphatic c1-C20 radical (n + 1) -valent which may be interrupted by -o-, -s-, -co-o-, -o-co-, -co-nr3-, -nr3-co-, -o-co-nr3-, - nr3-co-o- or -nr3-co-nr3-, x and y in each case independently are absent or represent -o-, -s-, co-o-, -o-co-, -co-nr3-, -nr3-co-, - o-co-nr3-, -nr3-co-o- or -nr3-co-nr3-, r, r1, r2 and r3 in each case independently represent h or c1-c7 alkyl radical ek, l, m and in each case independently are 1, 2 or 3. 1/1resumo patente de invenção: "materiais dentários à base de monômeros com propriedades de descolamento sob demanda". a presente invenção refere-se a um material restaurador dentário que compreende um composto polimerizável termolábil ou fotolábil de fórmula i: [(z1)m-q1-x)]k-t-[y-q2-(z2)n]l fórmula i, onde t representa um grupo termolábil ou fotolábil, z1 e z2 em cada caso independentemente representam um grupo polimerizável selecionado de grupos vinila, ch2=cr1-co-o- e ch2=cr1-co-nr2- ou um grupo adesivo selecionado de –si(or)3, -cooh, -o-po(oh)2, -po(oh)2, -so2oh e -sh, onde pelo menos um de z1 ou z2 é um grupo polimerizável, q1 em cada caso
