Abstract: A fractionation process of a methylene bridged polyphenylene polyisocyanate mixture obtained by phosgenating condensation product of aniline and formaldehyde is disclosed. In order to apply the above mixture to a variety of uses, the process separates the mixture into fractions by giving primary attention to the content of 4,4'- and 2,4'-isomer of diphenylmethane diisocyanate and at the same time reduces the content of impurities having acidity and hydrolyzable chlorine.

Abstract: A methylene-crosslinked polyarylamine is disclosed which contains a less amount of N-methylmethylenedianiline. A process for continuously preparing this kind of methylene-crosslinked polyarylamine is also revealed which comprises reacting aniline with formalin in the presence of hydrochloric acid under specific reaction conditions.

Abstract: IN A PROCESS FOR PRODUCING A BOARD BY USING AN ISOCYANATE ADHESIVE ACCORDING TO THE PRESENT INVENTION, A STABLE EMULSION CAN BE OBTAINED BY USING AN AMINE POLYOL, WHICH HAS BEEN OBTAINED BY THE ADDITION OF AN ALKYLENE OXIDE TO AN AMINE COMPOUND, OR A POLYESTER POLYOL CONTAINED IN ITS MOLECULE A NITROGEN COMPOUND UPON EMULSIFICATION OF AN ORGANIC POLYISOCYANATE IN WATER. THE USE OF THE AQUEOUS EMULSION SO OBTAINED OR THE AQUEOUS EMULSION FURTHER CONTAINING A METALLIC SALT OF AN ALIPHATIC CARBOXYLIC ACID HAVING 2 TO 28 CARBON ATOMS AS AN ADHESIVE, PARTICULARLY, AS AN ADHESIVE FOR A LIGNOCELLULOSE MATERIAL BRINGS ABOUT AN IMPROVEMENT IN THE PHYSICAL PROPERTIES OF THE RESULTING PRESSED BOARD INCLUDING STRENGTH, SHORTENS THE PRESSING TIME AND HEIGHTENS THE RELEASABILITY. IT IS THEREFORE AN INDUSTRIAL METHOD SUITED FOR THE EFFECTIVE PRODUCTION OF A HIGH-QUALITY PRESSED LIGNOCELLULOSE BOARD AT A LOW COST.
