Abstract: PROBLEM TO BE SOLVED: To provide a maleimide-norbornene copolymer composed of specific constituent units, capable of stably keeping the non-linear characteristics over a long period and giving a polymer material having good processability. SOLUTION: The objective copolymer is composed of (A) a constituent unit of formula I and (B) a constituent unit of formula II (R is H or methyl) and has a weight-average molecular weight of 5,000-15,000. The molar ratio of the constituent unit A to the constituent unit B is preferably 5:1 to 1:2. The copolymer can be produced by copolymerizing N-(4-hydroxyphenyl)maleimide and 2-norbornene at a molar ratio of preferably (1.2-1):1 in the presence of 0.05-5.0 wt.% of a radical polymerization initiator (e.g. acetyl peroxide) preferably at 60-80 deg.C for 10-50 hr and reacting the obtained copolymer with preferably 70-90 mol.% of a red dye of formula III using a solvent (e.g. tetrahydrofuran).

Abstract: PROBLEM TO BE SOLVED: To obtain a novel polymeric substance which does not show the relaxation of an aligned structure at high temperatures and having good heat stability and quadratic nonlinear optical properties by using a maleimide/styrene copolymer comprising three types of structural units having specified structures and having a specified number-average molecular weight. SOLUTION: This copolymer comprises structural units of formulas I, II and III (wherein R is H or methyl) and has a number-average molecular weight of 10,000-200,000. This is obtained by the following reactions. A mixture of N-(4-hydroxyphenyl)maleimide represented by formula I with an α-methylstyrene represented by formula II is heated to 50-100 deg.C in the presence of a radical polymerization initiator (e.g. acetyl peroxide) in a polymerization solvent (the ratio between the constituents of the mixture is in the range of 2:1 to 1:2). The obtained white solid is reacted with a red dye represented by formula IV (wherein R is H or methyl) in the presence of a condensing agent in a reaction solvent to obtain a compound comprising structural units of formulas I to III and being in the form of a reddish brown solid.

Abstract: PROBLEM TO BE SOLVED: To obtain a high-molecular material which undergoes controlled relaxation of an orientation structure at high temperature and has secondary nonlinear optical characteristics with good heat stability by subjecting a polymer obtained through the radical polymerization of a specified aniline derivative to diazo coupling with nitroaniline. SOLUTION: An aniline derivative of formula I (wherein R is H or methyl; and R is H, or methyl bound at a position other than the 4-position) is subjected to radical polymerization in the presence of 0.05-5.0 wt.% radical polymerization initiator at 50-100 deg.C for 10-50 hr to give a polymer having a weight-average molecular weight of 42,000 to 270,000. This polymer is subjected to diazo coupling with nitroaniline to introduce at least 20 mol.%, preferably 25-95 mol.%, azo groups, thus giving a nonlinear acrylamide polymer consisting of constituent units of formula II and those of formula II, and having a weight-average molecular weight of 50,000 to 300,000, an optimum poling temperature of 150-170 deg.C, and an initial d33 value at 80 deg.C of at least 200×10 esu.

Abstract: PURPOSE:To utilize resources effectively and efficiently by thermally decomposing mixed plastic waste, and finding the concentration of HCl. CONSTITUTION:A thermal decomposition reaction device 1 is provided with a heating furnace 2, a thermoregulator 3, a reaction tube 4, a sample feeding port 5, a thermocouple 7, a liquid receiving tank 8, cocks 9 and 9' and a gas pack 10. The sample obtained by grinding mixed plastic waste undergoes deoxi dation in inactive gas or in vacuum. Thereafter, the sample undergoes isothermal decomposition in the range of 260 - 360 deg.C or undergoes equal-speed/intermittent temperature-increasing thermal decomposition in the range from normal tempera ture to 360 deg.C. The sample is separated into gas product and residue. The concen tration of hydrogen chloride (HCl) in the gas product is measured. Thus, the amount of polyvinyl chloride-based resin in the sample is determined.

SOLUTION: The refractive index of the formed body is reversibly changed by irradiation of incoherent light or by stopping the irradiation, and further, the change width of the refractive index is >=0.005. From the viewpoints of easy production and a large change rate of the refractive index, the org. polymer which constitutes the formed body is preferably a linear or branched-chain org. polymer having polar org. groups on the side chains. Generally, the mol.wt. of the org. polymer ranges 1.000 to 500,000 of the weight average mol.wt., and preferably 5,000 to 300,000. Further, 2,6-diphenyl-4-(2,4,6-triphenylpyridinio)- phenolate is preferably added as an additive.
