Claims
- 1. A polymerizable composition comprising a mixture of an optically clear dead polymer, a reactive plasticizer in an amount to render the composition semi-solid and malleable, and an initiator, the dead polymer and reactive plasticizer exhibiting compatibility at temperatures not higher than 100° C., and wherein the polymerizable composition is semi-solid and malleable and, when polymerized, remains optically clear and exhibits low shrinkage.
- 2. A polymerizable composition according to claim 1 which is impact-resistant upon polymerization.
- 3. A polymerizable composition according to claim 1 which exhibits high fidelity replication upon polymerization.
- 4. A polymerizable composition according to claim 1 which exhibits dimensional stability upon polymerization.
- 5. A polymerizable composition according to claim 1 wherein the reactive plasticizer is less than about 50% by weight of the composition.
- 6. A polymerizable composition according to claim 1 wherein the reactive plasticizer is less than about 25% by weight of the composition.
- 7. A polymerizable composition according to claim 1 wherein the optically clear dead polymer is selected from the group consisting of polystyrenes, polysulfones, polyacrylates, polymethacrylates, polycarbonates, polyolefins, polyurethanes, copolymers and block copolymers.
- 8. A polymerizable composition according to claim 1 wherein the reactive plasticizer comprises reactive functional groups selected from the group consisting of acrylate, methacrylate, acrylic anhydride, acrylamide, vinyl, vinyl ether, vinyl ester, vinyl halide, vinyl silane, vinyl siloxane, (meth)acrylated silicones, vinyl heterocycles, diene, allyl, epoxies (with hardeners), and urethanes.
- 9. A polymerizable composition comprising a mixture of a biodegradable dead polymer, a reactive plasticizer in an amount to render the composition semi-solid and malleable, and an initiator, wherein the polymerizable composition is semi-solid and malleable and, when polymerized, exhibits low shrinkage.
