Abstract:
The invention relates to a dental restorative material which comprises a thermolabile compound of Formula I: [(Z1)m-Q1-X)]k-T-[Y-Q2-(Z2)n]l Formula I, in which T represents a thermolabile unit which contains at least one thermolabile group based on non-covalent interactions, 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, Q1 in each case independently is missing or represents an (m+1)-valent linear or branched aliphatic C1-C20 radical which can 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 missing or represents an (n+1)-valent linear or branched aliphatic C1-C20 radical which can 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 missing or represent —O—, —S—, CO—O—, —O—CO—, —CO—NR3— or —NR3—CO—, R, R1, R2 and R3 in each case independently represent H or a C1-C7 alkyl radical, k and l in each case independently are 0, 1, 2 or 3 and m and n in each case independently are 1, 2 or 3.
