Abstract

The present invention relates to improved internal mould release agents based on particular ammonium or metal salts of phosphoric acid esters, ammonium salts of carboxylic acids and/or ammonium or metal salts of sulfonic acids for producing cellular or compact, optionally glass fiber- and/or natural fiber-reinforced polyurethane mouldings. The polyurethane mouldings produced according to the invention may be laminated or coated with other materials.

with the proviso that at least one of R2, R3, R4 and R5 represents a hydrogen atom;
or
(3) a metal of the first main group of the periodic system of elements (Mendeléeff);
and, optionally, one or more components selected from the group consisting of b) and c), wherein:
b) comprises one or more ammonium salts of carboxylic acids corresponding to the formula (II)
R10COO−Z+ (II),
wherein:
R10 represents a hydrogen atom, a C1-C9 alkyl radical, or a C6-C10 aryl radical, which may optionally be substituted by C1-C3 alkyl groups;
and
Z represents:
(1) an NH4 group, or
(2) a group corresponding to the formula:
wherein:
R2 to R5:
are each independently selected from the group consisting of:
(i) a hydrogen atom,

and
(iii) correspond to the general formula:
wherein:
R8 and R9:
each independently represent a hydrogen atom or a C1-C10 alkyl radical:
m:
represents a whole number from 2 to 4;
and
n:
represents a whole number from 1 to 5;
with the proviso that at least one of R2, R3, R4 and R5 represents a hydrogen atom;
and
c) comprises one or more ammonium or metal salts of sulfonic acids corresponding to the general formula (III)
wherein:
R11:
represents a hydrogen atom, a C1-C9 alkyl radical, or a C6-C10 aryl radical, which may optionally be substituted by C1-C3 alkyl groups;
and
Y:
represents:
(1) an NH4 group;
(2) a group corresponding to the formula:
