Patent ID: 7157529

Claim:
A process of preparing a multi-layered macromolecule, said process comprising: (I) providing a solid particulate substrate capable of reacting with a first lot of silane bonding agent; (II) contacting the solid particulate substrate with a first lot of silane bonding agent and allowing the solid particulate substrate to react with the first lot of silane bonding agent; (III) contacting the product formed in step (II) with a first lot of base macromolecule selected from the group consisting of (a) dendrimers and, (b) hyperbranched polymers and allowing the base macromolecule and the product from step (II) to react with each other to form a first layer; (IV) contacting the product from step (III) with a second lot of silane bonding agent and allowing the second lot of silane bonding agent and the product from step (III) to react with each other; (V) providing a second lot of base macromolecule; (VI) contacting the second lot of base macromolecule with a third lot of silane bonding agent and allowing the third lot of silane bonding agent and the second lot of base macromolecule to react to form a reactive product; (VII) combine the product from step (IV) and the product from step (VI) in the presence of water and allow the product from step (IV) and the product from step (VI) to react to form a multi-layered macromolecule.
