摘要： The present invention provides a novel polycarbonate diol and a polyurethane using the polycarbonate diol as raw materials. The novel polycarbonate diol produces polycarbonate diol-based polyurethane which has a high degree of hardness, superior abrasion resistance, and superior hydrophilicity, and is usable for an application such as a paint, a coating agent, a synthetic leather, an artificial leather, and a highly-functional elastomers, or the like. The present invention also provides an active-energy radiation curable polymer composition giving a cured film having a superior contamination resistance and high degree of hardness. The present invention is obtained, for example, by reacting specific two types of diols with diester carbonate in the presence of a transesterification catalyst being a compound using a metal of Group 1 or 2 on the periodic table. The present invention provides a polycarbonate diol wherein the metal content of the transesterification catalyst is 100 weight ppm or less, a polyurethane obtainable by using this polycarbonate diol and an active-energy radiation curable polymer composition containing the urethane(meth)acrylate oligomer which is obtained from the polycarbonate diol.

摘要： A method of preparing a polycarbonate composition in a polymerization system that includes a monomer mixing unit, an oligomerization section, and a polymerization section. The method includes melt polymerizing a dihydroxy compound with a diaryl carbonate compound in the presence of a quaternary phosphonium catalyst to produce the polycarbonate composition having a phosphorus-containing byproduct of at least one of the quaternary phosphonium catalyst or of the diaryl carbonate compound. The method further includes recycling the phosphorus-containing byproduct into the monomer mixing unit of the polymerization system and removing the polycarbonate composition from the polymerization system. The recycle stream has a phosphorus concentration of greater than or equal to 40 parts per million by weight.

摘要： Described is a transparent polymer-based composite and a method for preparing a transparent polymer-based composite. The transparent polymer-based composite includes an activated polycarbonate and one or more nanoparticles grafted to the activated polycarbonate. The activated carbonate is formed via a transcarbonation reaction of a mixture of a carbonic acid species having terminal ester groups and a bisphenol-A with sodium hydroxide and ortho-dichlorobenzene. The transparent polymer-based composite may be used to replace the glass front-sheet of solar panels for photovoltaic applications.

摘要： A polycarbonate resin composition may include a first polycarbonate resin and a second polycarbonate resin, which a molded article may include, and a multilayer body may have a resin layer A including the polycarbonate resin composition and a resin layer B including a resin different from the resin layer A. The first polycarbonate resin may include 40% by weight or more of a structural unit of formula (1)




The second polycarbonate resin may include less than 40% by weight of the structural unit of formula (1). The weight ratio of the first polycarbonate resin to the second polycarbonate resin, the first polycarbonate resin/the second polycarbonate resin, may be in a range of from 55/45 to 99/1. The polycarbonate resin composition may have two or more glass transition temperatures.
