| titleOfInvention | Urethane polymers containing a tertiary nitrogen atom, and their production |
| abstract | A tertiary nitrogen atom-containing urethane polymer which comprises units of the following formulas (I) and (II) as the essential components and units of the following formulas (III), (IV) and (V) as the optional components, the content of the unit of the formula (I) being not less than 10 milliequivalents in terms of the tertiary nitrogen atom per kilogram of the urethane polymer, and has a molecular weight of not less than 500: <IMAGE> (I) [CONHR5NHCO] (II) [OR6O] (III) [COR7CO] (IV) [NHR8NH] (V) wherein R1 and R2 are each a C1-C4 alkyl group and, when taken together with the adjacent nitrogen atom to which they are attached, represent a nitrogen-containing heterocyclic group, R3 is a C1-C4 alkyl group, R4 is an optionally branched C1-C8 alkylene group, m is a positive integer and n is zero or a positive integer but m+n is a number which can provide the unit of the formula (I) with a molecular weight of 131 to 6998 and the bondings in the unit of the formula (I) may be in random and/or block, R5 is a residue of an organic diisocyanate, R6 is an optionally branched C1-C8 alkylene group, an aromatic group optionally substituted with one or more C1-C4 alkyl groups and/or one or more halogen atoms or a residue of a polyetherdiol thereof, R7 is a residue of a dicarboxylic acid and R8 is a residue of a diamine or a residue of a hydrazine, which is effective in improvement of resistance to color change due to gas. |
