摘要: The purpose of the present invention is to provide: a novel polymer which has an electro-optical effect; a method for producing such a polymer; and a light control element which uses such a polymer. The present invention relates to a non-crosslinkable polycarbonate which contains a moiety that has electro-optical characteristics. The present invention also relates to a method for producing a polycarbonate, which comprises a step for reacting a bisphenol compound, a diol compound that has electro-optical characteristics, and a phosgene in the presence of an acid binding agent and solvent. The present invention also relates to a light control element which comprises such polycarbonate.

摘要: To provide a non-halogen-based flame retardant for obtaining a flame-retardant product having high flame retardancy and a good appearance and a flame-retardant product comprising the same.
An organic phosphorus-based compound which satisfies the following requirements (i) to (viii) and is represented by the following formula (1):
(i) the organic purity should be not lower than 98 %;
(ii) the solubility in 20°C water should be not higher than 0.1 g/100 g of water;
(iii) the total halogen component content should be not higher than 1,000 ppm;
(iv) the total volatile organic matter content should be not higher than 800 ppm;
(v) the Δ pH value should be not larger than 1.0;
(vi) the volume standard median diameter should be not larger than 30 µm;
(vii) the maximum particle diameter should be not larger than 200 µm; and
(viii) the standard deviation represented by the following formula (6) should be not larger than 20 µm. Standard deviation = d 84 % + d 16 % / 2
d84 %: particle diameter at a point where the cumulative curve becomes 84 % (µm)
d16 %: particle diameter at a point where the cumulative curve becomes 16 % (µm)
(In the above formula, R 2 and R 5 may be the same or different and are each a phenyl group which may have a substituent, naphthyl group which may have a substituent, anthryl group which may have a substituent, or branched or linear alkyl group having 1 to 4 carbon atoms which may have an aromatic substituent. R 1 , R 3 , R 4 and R 6 may be the same or different and are each a hydrogen atom, branched or linear alkyl group having 1 to 4 carbon atoms, phenyl group which may have a substituent, naphthyl group which may have a substituent, or anthryl group which may have a substituent.)-
