Title: Production of polyamide
Inventor: CHIBA SHUJI
IPC: C08G69/04
Filed: 1989-02-07
Abstract: PURPOSE:To obtain a high-MW polyamide easily within a short polymerization time by swelling a specified oligoamide or polyamide with an organic solvent and effecting its polymerization in a heating medium. CONSTITUTION:In the production of a high-MW polyamide by effecting the polycondensation of an oligoamide or a polyamide formed from an aliphatic, alicyclic and/or aromatic diamines and/or aromatic dicarboxylic acid, an aminocarboxylic acid or a lactam in a heating medium by blowing an inert gas into the system, said oligoamide or said polyamide is swollen with an organic solvent before the polycondensation. It is desirable that the polyamide be in a state more highly swollen with the heating medium when the polyamide is polymerized in the heating medium because by-products, etc., can be smoothly removed therefrom. Therefore, the polyamide can be more easily swollen with the heating medium by previously swelling it with the organic solvent.

IPC: C07C269/00
Filed: 1988-02-10
Abstract: PURPOSE:To increase yield of 4,4'-MDU, by treating a condensation reaction product of N-phenylcarbamate with a methylenating agent in an aromatic system, depositing and separating 4,4'-MDU and recondensing the resultant mother liquor with a methylenating agent. CONSTITUTION:N-Phenylcarbamate is condensed with a methylenating agent (e.g., formaldehyde) in the presence of an aqueous solution of an acid as a catalyst to provide a reaction product, which is then treated with an aromatic solvent (preferably benzene, toluene or xylene) to preferentially deposit 4,4'-methylene diphenyldicarbamate (4,4'-MDU). The deposited substance is then separated from the mother liquor by solid-liquid separation. The mother liquor containing the unreacted N-phenylcarbamate, 2,4'- and 2,2'-MDU and polynuclear substances is recondensed with the methylenating agent in the presence of an aqueous solution of an acid to convert the unreacted N-phenylcarbamate into MDU and 2,4'- and 2,2'-MDU into polynuclear substances. Thereby, the amount of the formed 2,4'- and 2,2'-MDU having low availability is reduced.

Title: Polishing process for compound semiconductor substrate
Inventor: KOMATA CHIKAFUMI
IPC: H01L21/304
Filed: 1989-02-08
Abstract: PURPOSE:To enhance the flatness by a method wherein the surface pressure exceeding specified value is applied on substrates to polish the surface in recessed shape and then the secondary polishing process is performed using a soft abrasive cloth. CONSTITUTION:During the primary polishing process, a polishing solution 5 containing abrasive grain and a hard abrasive cloth 2 are used while the surface pressure exceeding 100g/cm<2> is applied on wafers 4 to polish the surface in recessed shape. Next, during the secondary polishing process, the polishing solution 5 containing no abrasive grain and the abrasive cloth 2 with a foaming layer are used to polish the plane in flat shape. In the said processes, the polishing amount in the wafer 4 peripheral parts is decreased by the abrasive grain in the primary polishing while the polishing amount in the central part is increased so that the wafer 4 surface may be polished in recessed shape. At this time, the polishing amount in the peripheral parts is controlled by the surface pressure in anticipation of the sag during the secondary polishing process. Through these procedures, the wafer 4 peripheral parts, even if excessively polished in the secondary polishing process, can be flattened.
