Carbodiimide-containing compositions and method for the production and use thereof

摘要

Carbodiimide containing compositions include diilsocyenates, polyols, and liquid carbodiimide of the formula;
where R1, R2, R4 and R6 are each independently C3-C6-alkyl, and R3 and R5 are each independently C1-C3-alkyl.

1. A composition comprising:
a polyether ester polyol that is liquid at temperatures of 30° C.-80° C., and/or a polyester polyol that is liquid at temperatures of 30° C.-80° C.; a carbodiimide of the formula (I) that is liquid at room temperature where R1, R2, R4 and R6 are each independently C3-C6-alkyl, and
R3 and R6 are each independently C1-C3-alkyl, and a diisocyanate, where a ratio of diisocyanate to polyol is 20-50:100 parts by weight.
