摘要:
Apparatus for decomposing a polyurethane resin and recovering the decomposed polyurethane resin as a polyamine compound and a polyol compound. The apparatus includes a first reactor that decomposes the polyurethane resin as the target compound of hydrolysis decomposition; a second reactor that hydrolyzes the decomposed target compound of decomposition with either one of supercritical water and high-temperature high-pressure water to a decomposition product mixture; a water supplier that feeds either one of supercritical water and high-temperature high-pressure water to the second reactor; and a post-processor that causes the decomposition product mixture discharged from the second reactor to be subjected to a post treatment procedure, such as dehydration, addition, distillation, separation, and liquid separation to recover the polyamine compound and the polyol compound.
摘要:
A method of recovering a decomposition product from a polyurethane, the method comprising the steps of thermally decomposing a polyurethane into a liquid containing a polyol and a urea compound which is soluble in the polyol, and solids containing a urea compound which is insoluble in the liquid in the presence of a polyamine compound at a temperature of 120 to 250° C.; removing the solids; hydrolyzing the residue with water retained at a high temperature of 200 to 320° C. and a high pressure; and recovering the resulting polyamine and/or polyol.

A recording reproducing apparatus reproduces a rotary recording medium which is accommodated within a jacket. The apparatus has a jacket opening enlarging device which is horizontally movable over a turntable, in the vicinity of a lateral inserting opening. For loading the recording, the jacket is inserted into the rear part of the reproducing apparatus where the record is captured and then the jacket is pulled out, leaving the record on the turntable. The jacket opening enlarging device comprises upper and lower enlarging members aligned with the inserting opening and pivotally coupled together to open and close by swinging upwardly and downwardly respectively. Fingers on the enlarging members project towards the inserting opening, which are close to each other when the jacket opening enlarging device is in the vicinity of the inserting opening. A rotating mechanism swingably opens the upper and lower enlarging members so that the fingers open the jacket engaging with rims as the jacket opening enlarging device moves toward the rear part. An enlarging member locking mechanism interlocks the upper and lower enlarging members for keeping them closed to shut the inserting opening when the jacket opening enlarging device is positioned in the vicinity of the inserting opening, and release the interlock upon insertion of the case.

摘要:
A thermoplastic polymer compound can be obtained by allowing a compound having a bivalent organic group to react with a polyoxyalkylene diol obtained by addition-polymerization of an urea compound having a partial structure refractivity of 14 to 35 and a dipole moment of 2.5 D to 5.5 D with an alkylene oxide. A thermoplastic polymer composition comprises the thermoplastic polymer compound and an inorganic salt of an alkali metal or the like. The polymer compound and the polymer composition are useful as an antistatic agent and have excellent antistatic properties and excellent transparency.
