The phosphorus-based oxazine compounds of the present invention can provide better fire-resistant characteristics, while the preparation method for the phosphorus-based oxazine compound of the present invention can offer high yields and/or high purity phosphorus-based oxazine compounds. | 07-02-2009 |
| 20090182116 | MANUFACTURE OF PHOSPHORUS-CONTAINING DIAMINES AND THEIR DERIVATIVES - A series of novel phosphorus-containing compounds having the following formula are disclosed: | 07-16-2009 |
| 20090215967 | MANUFACTURE OF NOVEL EPOXY RESINS SEMI-THERMOSETS AND THEIR HIGH TG THERMOSETS FOR ELECTRONIC APPLICATIONS - An active-hydrogen-containing (carboxyl or hydroxyl) phosphorus compound is provided. An epoxy resin semi-thermoset formed by bonding the phosphorus compound to an epoxy group is also provided. A flame-retardant epoxy resin thermoset is formed after reacting the epoxy resin semi-thermoset with a curing agent. The epoxy resin thermoset possesses excellent flame retardancy, heat stability, and high glass transition temperature (Tg), does not produce toxic and corrosive fumes during combustion, and thus is an environmentally friendly flame-retardant material. | 08-27-2009 |
