20110040066 | POLYCARBONATES HAVING REARRANGEMENT STRUCTURES, CYCLIC AND LINEAR OLIGOMERS AND ALSO FLOW BEHAVIOR - The present invention relates to compositions having improved rheological properties which are based on polycarbonate having rearrangement structures and cyclic and linear oligomers and also mouldings and extrudates composed of these polycarbonate compositions. | 02-17-2011 |
20130150548 | PREPARATION OF HOMOPOLYMER AND COPOLYMERS OF (PHOSPHONYL)AROMATIC DIESTERS AND ACIDS - The composition of a homopolymer of (phosphonyl) aromatic diester compound using a catalyst and a glycol is provided. Further, the composition of a copolymer of the (phosphonyl) aromatic diester compound using a catalyst, a glycol and a second diester is provided. These polymers find application as flame retardants during synthesis of various polymeric materials. | 06-13-2013 |
20140187736 | Branched Polycarbonate and Method for Preparing the Same - A method for preparing branched polycarbonate includes: preparing a first raw material by mixing and reacting an aromatic dihydroxy compound, diaryl carbonate, and about 60 ppb (weight) to about 140 ppb (weight) of a catalyst with respect to the amount of aromatic dihydroxy compound; preparing a second raw material by mixing and reacting an aromatic dihydroxy compound, diaryl carbonate, a phosphorus branching agent, and about 350 ppb (weight) to about 450 ppb (weight) of the catalyst with respect to the amount of aromatic dihydroxy compound; and melt-polymerizing about 100 parts by weight of the first raw material and about 1 part by weight to about 20 parts by weight of the second raw material. The branched polycarbonate prepared by the method can exhibit excellent properties in terms of heat resistance, color stability and/or fluidity due to small catalyst amount. | 07-03-2014 |
