Estimating the term…
Hyperbranched polymers are prepared by a process in which a monomer having the form Ax is reacted with another monomer of the form By, where A and B are functional groups that do not react with themselves, but do react with each other. The process allows synthesis of hyperbranched polymers having a single type of terminal functional group from comonomers, each of which has a single type of functional group. The invention allows greater flexibility in the preparation of a larger variety of different hyperbranched polymers and enables hyperbranched polymers to be prepared at a lower cost as compared with conventional processes using monomers having two types of functional groups that react during polymerization.
A hyperbranched polyurea, polyurethane, polyamidoamine, polyamide or polyester, comprising:
A process for preparing a hyperbranched polyurea, polyurethane, polyamidoamine, polyamide or polyester, comprising:
A hyperbranched polyurea, polyurethane, polyamidoamine, polyamide or polyester network, comprising:
A compound that comprises the reaction product of a hyperbranched polymer having terminal functional groups, and a silicon-containing compound.
A hyperbranched polymer network comprising the cross-linked reaction product of a hyperbranched polymer having an organosilicon exterior layer and a difunctional or multifunctional cross-linking molecule, wherein the hyperbranched polymer having an organosilicon exterior layer is the reaction product of a hyperbranched polymer having terminal functional groups reacted with a silicon-containing compound.
