    摘要： POLYPARABANIC ACID DERIVATIVES WHICH CONTAIN THE STRUCTURAL UNIT:

    -(2,4-DI(Z=),5-X,5-Y-IMIDAZOLIDIN-1,3-YLENE)-

    REPREATEDLY IN ONE MOLECULE, IN THIS STRUCTURAL UNIT Z=O OR S, X AND Y, WHICH MAY BE THE SAME OR DIFFERENT, REPRESENT RADICAL OF THE FORMULA -NR1R2, -OR1 OR -SR1, WHERE R1 REPRESENTS AN OPTIONALLY SUBSTITUTED AKYL, OPTIONALLY SUBSTITUTED ALKYL, OPTIONALLY SUBSTITUTED CYCLOALKYL OR OPTIONALLY SUBSTITUTED ARYL RADICAL, AND R2 REPRESENTS HALOGEN OR HAS THE SAME MEANING AS R1, OR R1 AND R2 TOGETHER CAN ALSO REPRESENT AN ALYLENE OR ARYLENE RADICAL WHICH JOINS X AND Y TOGETHER TO FORM A RING, AND PROCESS FOR THEIR PRODUCTION.

    摘要： Novel cyclic urea derivatives containing silicon atoms have the general formula

    WHEREIN R is a hydrocarbon radical optionally being interrupted by oxygen atoms in ether linkages, R'' and R'''' (same or different) are hydrocarbon radicals, halohydrocaron radicals, cyanohydrocarbon radicals, or alkoxy radicals, and R'''''' is a hydrocarbon radical.

    摘要： NOVEL CYCLIC UREA DERIVATIVES CONTAINING SILICON ATOMS HAVE THE GENERAL FORMULA

    1-R"'',3-R,4-R'',4-R"-1,3-DIAZA-4-SILACYCLOPENTAN-2-ONE

    WHEREIN R IS A HYDROCARBON RADICAL OPTIONALLY BEING INTERRUPTED BY OXYGEN ATOMS IN EITHER LINKAGES, R'' AND R" (SAME OR DIFFERENT) ARE HYDROCARBON RADICALS, HALOHYDROCARBON RADICALS, CYANOHYDROCARBON RADICALS, OR ALKOXY RADICALS, AND R"'' IS A HYDROCARBON RADICALS. THESE 2,5-DIAZA--3-SILACYCLOPENTANONES CAN BE PRODUCED, ACCORDING TO THE INVENTION, BY REACTING AN AMINOMETHYLALKOXYSILANE OF THE GENERAL FORMULA R"''-NH-CH2-SI(-R'')(-R")-O-X (R'', R" AND R"'' AS ABOVE; X=ALKYL) AT A TEMPERATURE BETWEEN 0 AND 250*C. WITH AN ISOCYANATE OF THE GENERAL FORMULA RNCO (R AS ABOVE) AND RECOVERING THE PRODUCT BY DISTILLATION UNDER REDUCING PRESSURE. THESE PRODUCTS ARE SUITABLE FOR PROMOTING THE ADHESION OF SYNTHETIC RESINS TO SILICEOUS SURFACES, FOR USE AS INTERMEDIATES FOR ORGANOPOLYSILOXANE RESINS, AND FOR USE AS CROSS-LINKING AGENTS IN WATER-REACTIVE ORGANOPOLYSILOXANE PREPARATIONS.
