Abstract
Abstract Heat resistant polymers connected by ester and/or urethane groups and optionally amide- and/or imide groups and/or hydantoin and/or isocyanurate rings are obtained by crosslinking the polymers with trishydroxy alkyl triazolidine -3,5-diones.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
Cross-linked polymers which are linked by ester and/or urethane groups and which optionally contain amide and/or imide groups and/or isocyanurate and/or hydantoin rings in co-condensed form or are mixed with the corresponding polymers, wherein said cross-linking component is derived from N,N',N"-tris-hydroxyalkyl triazolidine-3,5-diones corresponding to the following general formula: ##STR17## wherein R 1 , R 2 , R 3 and R 4 each independently represents hydrogen, an optionally substituted aliphatic, cycloaliphatic or atomatic radical and X represents O or S.
Claim 2
Dependent Claim
79 words
Cross-linked polymers which are linked by ester and/or urethane groups and which optionally contain amide and/or imide groups and/or isocyanurate and/or hydantoin rings in co-condensed form or are mixed with the corresponding polymers, wherein said cross-linking component is derived from N,N',N"-tris-hydroxyalkyl triazolidine-3,5-diones corresponding to the following general formula: ##STR17## wherein R 1 , R 2 , R 3 and R 4 each independently represents hydrogen, an optionally substituted aliphatic, cycloaliphatic or atomatic radical and X represents O or S.
Claim 3
Dependent Claim
71 words
Polymers as claimed in claim 1, wherein in the general formula R 1 , R 2 , R 3 and R 4 the same or different represent hydrogen, optionally halogen-substituted C 1 -C 10 alkyl radical, C 4 -C 8 cycloalkyl radical, C 7 -C 17 aralkyl radical or a C 6 -C 16 aryl radical optionally substituted by halogen, C 1 -C 6 alkyl and/or C 1 -C 6 alkoxy.
Claim 4
Dependent Claim
12 words

Claim 5
Dependent Claim
19 words
Heat-resistant coating materials, films, powders, adhesives or shaped articles obtained from solutions or mixtures as claimed in claim 3.
Claim 6
Dependent Claim
14 words
Lacquers, particularly wire lacquers obtained from solutions or mixtures as claimed in claim 3.
