(METH)ACRYLOYL-CONTAINING MATERIALS, COMPOSITIONS, AND METHODS |
摘要 |
<p>Di-, tri-, and/or tetra-(meth)acryloyl-containing materials and compositions are provided. Such materials and compositions can preferably be hardened, without undue shrinkage, to provide hardened materials and/or compositions with properties useful, for example, in dental applications. In one aspect, the present invention provides a compound of the formula (Formula I) wherein: each X independently represents an oxygen atom (O) or a nitrogen atom (N); Y and A each independently represent an organic group, with the proviso that Y does not represent -NHCH<SUB>2</SUB>CH<SUB>2</SUB>- if (i) p = O and R<SUP>1</SUP> represents -C(O)C(CH<SUB>3</SUB>)=CH<SUB>2</SUB>, and/or (ii) q = 0 and R<SUP>2</SUP> represents -C(O)C(CH<SUB>3</SUB>)=CH<SUB>2</SUB>; m = 1 to 5; n = 0 to 5; p and q are independently 0 or 1; and R<SUP>1</SUP> and R<SUP>2</SUP> each independently represent H, -C(O)CH=CH<SUB>2</SUB>, or -C(O)C(CH<SUB>3</SUB>)=CH<SUB>2</SUB>.</p> |
