摘要:
The invention relates to the combined use of metal salts of ricinoleic acid with reactive amines in the preparation of polyurethane foams (PUR foams) and of their solutions in aqueous or organic solvents in the preparation of polyurethane foams in combination with reactive amines.
摘要:
The invention relates to a process for preparing polyurethane foams (PUR foams) which uses reactive amines of the formula where n is 1 to 4, R1 and R2 are —(CH2—CH2—O)xH, —(CH2—CH(CH3)—O)xH, or —((CH2—CH(CH2—CH3)—O)xH, and x is 0, 1, 2, 3 or 4, with the proviso that, at least one of the indices in the molecule is greater than 0, in combination with metal salts.
