    摘要： The resins resulting from converting dicyclopentadiene-phenol adducts to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from therma, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.

    摘要： Macromolecules in the shape of three-dimensional kites, barbells, and other shapes are disclosed. The shaped macromolecules are prepared the reaction of one or more dendritic polymers and a linear polymer. The kite-shaped macromolecules are dendritic polymers attached at either their focal points or at an outer to a long carbon chain group. The barbell macromolecules have dendritic polymers at either end of the molecule, which polymers are connected together through the focal points of each by a suitable connecting substituent such as a linear polymer. The shaped macromolecules are used in specialty medical and technological applications including such as drug delivery agents, imaging materials, molecular devices, thin film devices, surface modifiers, transport agents, compatibilizers, rheology control agents, molecular ball bearings, molecular dipoles, non-linear optical materials, medical imaging agents, membrane and cell modifiers, complexing agents, adhesives, interface strengthening agents, and the like.
