摘要：
Uncured dental composite material comprising (a) a composition comprising at least one compound of the formula: ** Formula ** where: n>； = 0 to 5； R1 and R2 are each independently H or methyl； R5 and R6 are independently selected from divalent organic radicals, each comprising 1-20 carbon atoms each； each Q1 is independently selected and is a divalent organic radical comprising 1-50 carbon atoms； Z1 and Z2 are independently selected and are represented by the formula ** Formula ** where i>； = 2-10； g and h are each independently 0 or 1, with the proviso that at least one of g and h are not zero； and X and Y are each independently H or a C1-C4 alkyl group； R3 and R4 are each independently selected and are represented by the formula ** Formula ** where X and Y are as defined above, p, q, and r are each independently 0-50, with the proviso that at least one of qor must not be zero if p is not zero, that s is 2 to 10, and that the total number of carbon atoms in the chain must be greater than or equal to 9. (b) at least 10% by weight radiopaque filling； and (c) a polymerization initiator.Material compuesto dental no curado que comprende (a) una composición que comprende al menos un compuesto de fórmula:**Fórmula** donde: n>；= 0 a 5； R1 y R2 son cada uno independientemente H o metilo； R5 y R6 se seleccionan independientemente entre radicales orgánicos divalentes, comprendiendo cada uno 1-20 átomos de carbono cada uno； cada Q1 se selecciona independientemente y es un radical orgánico divalente que comprende 1-50 átomos de carbono； Z1 y Z2 se seleccionan independientemente y están representados por la fórmula**Fórmula** donde i>；= 2-10； g y h son cada uno independientemente 0 o 1, con la condición de que al menos uno de g y h no son cero； y X e Y son cada uno independientemente H o un grupo alquilo C1-C4； R3 y R4 se seleccionan cada uno independientemente y están representados por la fórmula**Fórmula** donde X e Y son como se han definido anteriormente, p, q, y r s
