20120130022 | Method for Providing a Side-Chain Dendrimer Vesicle - A method for making a side-chain dendrimer vesicle includes the following steps. At first, there is provided a random copolymer with a narrow distribution of molecular weights by active polymerization and chemical modification. Then, chemical modification is executed to graft various generations of dendrimers to the random copolymer to provide a side-chain dendritic random copolymer with various generations. Two steps of emulsification are taken to induce macromolecular self-assembling of the side-chain dendritic random copolymer solution to form the macromolecular vesicle. The side-chain dendrimer includes C | 05-24-2012 |
20120130126 | Processes of Synthesizing Multi-Functional Phosphorus-Containing Epoxy Curing Agent - A series of curing agents are provided. The curing agents are multi-functional and phosphorus-containing. The curing agents have excellent processability to be used as an epoxy resin curing agent.

20130131301 | Method for Making Waterborne Polyurethane with a Reactive Functional Group and a Nanocomposite Made of the Same - Disclosed is a method for making waterborne polyurethane with a reactive functional group. The method includes the step of introducing a short-chain diol monomer with a reactive functional group into waterborne polyurethane polymer by pre-polymerization to provide a polyurethane pre-polymer with the reactive functional group connected to a side chain and the step of reacting the pre-polymer with hydrophilic diamine for chain extension and inter-crosslink to provide waterborne polyurethane with different crosslink degree. The short-chain diol monomer is expressed by structural formula (I) and the polyurethane pre-polymer with the reactive functional group connected to the side chain is expressed by structural formula (II) as follows: | 05-23-2013 |
20130144026 | Method for Making a Thermo-Stable and Transparent Resin - Disclosed is a method form making a thermo-stable and transparent resin. In the method, at first, polyborosiloxane is syhthesized by hydrolyzing and condensing a boron-containing compound, used as a precursor, and a silane compound. Then, epoxy group-containing polyborosiloxane is synthesized by grafting an epoxy group to the polyborosiloxane. Finally, an epoxy/PGB composite is synthesized by reacting the epoxy group-containing polyborosiloxane with epoxy for consolidation, thus providing a homogenous, stable, net-shaped composite. | 06-06-2013 |
