NEW POLYOLS AND USES THEREOF

摘要

The present invention relates to new polyols and uses thereof, specifically polyols of the non-alkoxylated hydroxylated Mannich base type that can be produced by condensation of at least one phenolic derivative and at least one aldehyde with a mixture of: a) mono or dialkanolamines; and b) aliphatic diamines containing a tertiary amino group and a primary amino group, or aliphatic diamines containing a tertiary amino group and a secondary amino group. The invention also relates to compositions comprising new polyols or Mannich bases and to formulations for rigid polyurethane foams that comprise said compositions.
