Heat-insulating body

Heat insulating bodies

The instant invention is directed to novel compounds and the use thereof in producing polyurethane resins. The compounds generally correspond to the following formula: ##STR1## wherein n is an integer of from 1 to 5,

Odorless catalysts for the synthesis of polyurethanes

Cellular and non-cellular polyurethane plastics and semi-hard polyurethane foams which are prepared by the use of novel Mannich bases of the general formula ##STR1## and which have improved strength and tear resistance are disclosed herein.

Polyurethanes prepared with novel Mannich bases

New chemical compounds containing the radicals --CO--NH--CH.sub.2 --OR; ##STR1## wherein R is an alkyl radical having one to six carbon atoms and R.sub.1 is an alkylene radical having one to six carbon atoms and a process for making polyurethanes with the new compounds as a catalyst are provided.

Nitrogen containing chemical compounds and a process for making

New chemical compounds containing at least one aliphatically bound tertiary nitrogen atom and at least one --CO--NH--CH.sub.2 --OR radical wherein R is an alkyl group of one to six carbon atoms and a process for making polyurethanes with the new compounds as a catalyst are provided.
