Die Erfindung betrifft ein Einstufen-Verfahren zur Herstellung von zelligen oder vorzugsweise kompakten Polyurethan-Polyharnstoff-Formkörpern, vorzugsweise mit Hilfe der Reaktionsspritzgußtechnik, durch Umsetzung von organischen Polyisocyanaten, Polyolen und gegebenenfalls substituierten Diaminoazobenzolen, vorzugsweise 4,4'- und/oder 2,4'-Diaminoazobenzolen, Diaminoazopyridinen und/oder deren Oxide in Gegenwart von Katalysatoren sowie gegebenenfalls Treibmitteln, Hilfs- und Zusatzstoffen.
A highly permeable aromatic polyimide gas separation membrane and the process of using it are disclosed. The aromatic polyimide has the formula
wherein
, or mixtures thereof, -X, -X1, -X2 and -X3 independently are alkyl groups having 1 to 6 carbon atoms or aromatic groups having 6 to 13 carbon atoms, and -Z is -H, -X, -X1, -X2, or -X3; and R is
or mixtures thereof.
A photosensitive resin precursor composition exhibiting an excellent film thickness uniformity contains: a heat resistant resin precursor polymer; a radiation sensitive compound; and a solvent expressed by formula (1):
R1 represents an alkyl group having a carbon number in the range of 1 to 3. R2, R3, R4, and R5 each represent hydrogen or an alkyl group having a carbon number in the range of 1 to 3, and 1 represents an integer in the range of 0 to 3.
A low temperature curable epoxy resin composition which comprises: an epoxy component that contains an epoxy compound having per molecule at least two epoxy groups and that is liquid at 25°C; an aromatic amine based curing agent that contains an aromatic amine compound having per molecule at least two amino groups directly bonded to the aromatic ring and that is liquid at 25°C; andMg(II) acetylacetonate as a cure accelerator. The composition, which contains a novel cure accelerator using a metal complex, exhibits high stability at room temperature while lowering a cure temperature or shortening a cure time.
