Use of oxyimide-comprising copolymers or polymers as flame retardants, stabilisers, rheology modifiers for plastic materials, initiators for polymerisation- and grafting processes, crosslinking- or coupling agents and also plastic moulding compounds comprising such copolymers or polymers
View Patent ↗The present invention relates to the use of oxyimide-comprising copolymers or polymers as flame retardants for plastic materials, stabilisers for plastic materials, rheology modifiers for plastic materials and also as initiators for polymerisation- and grafting processes and/or crosslinking- or coupling agents. In addition, the present invention relates to plastic material molding compounds which comprise such copolymers or polymers.
1. A method for producing a copolymer or polymer comprising at least one of the following structural elements:
the method comprising:
reacting a copolymer or polymer comprising a maleic anhydride unit or an itaconic anhydride unit with an amine according to the general formula IV:
H 2 N—O—R (IV),
wherein, respectively independently of each other,
R is an optionally substituted alkyl radical with 1 to 18 carbon atoms, an optionally substituted cycloalkyl radical with 6 to 22 carbon atoms, an optionally substituted aryl radical with 6 to 36 carbon atoms, or an optionally substituted acyl radical with 2 to 18 carbon atoms or hydrogen,
* is a binding site in the copolymer or polymer,
n is 0 or 1, and
X is methyl.
2. The method of claim 1 , which comprises reacting a copolymer or polymer comprising a maleic anhydride unit with an amine according to the general formula IV.
3. The method of claim 1 , which comprises reacting a copolymer or polymer comprising an itaconic anhydride unit with an amine according to the general formula IV.
4. The method of claim 1 , wherein R is an optionally substituted alkyl radical with 1 to 18 carbon atoms.
5. The method of claim 1 , wherein R is an optionally substituted cycloalkyl radical with 6 to 22 carbon atoms.
6. The method of claim 1 , wherein R is an optionally substituted aryl radical with 6 to 36 carbon atoms.
7. The method of claim 1 , wherein R is an optionally substituted acyl radical with 2 to 18 carbon atoms or hydrogen.
8. The method of claim 1 , wherein n is 0.
9. The method of claim 1 , wherein n is 1.
10. The method of claim 2 , wherein R is an optionally substituted alkyl radical with 1 to 18 carbon atoms.
11. The method of claim 2 , wherein R is an optionally substituted cycloalkyl radical with 6 to 22 carbon atoms.
12. The method of claim 2 , wherein R is an optionally substituted aryl radical with 6 to 36 carbon atoms.
13. The method of claim 2 , wherein R is an optionally substituted acyl radical with 2 to 18 carbon atoms or hydrogen.
14. The method of claim 2 , wherein n is 0.
15. The method of claim 2 , wherein n is 1.
16. The method of claim 3 , wherein R is an optionally substituted alkyl radical with 1 to 18 carbon atoms.
17. The method of claim 3 , wherein R is an optionally substituted cycloalkyl radical with 6 to 22 carbon atoms.
18. The method of claim 3 , wherein R is an optionally substituted aryl radical with 6 to 36 carbon atoms.
19. The method of claim 3 , wherein R is an optionally substituted acyl radical with 2 to 18 carbon atoms or hydrogen.
20. The method of claim 3 , wherein n is 0.
