Abstract

The invention relates to a compound of the following formula (I): to its method for making it and to its uses for preparing a polymer useful for increasing the heat resistance of polymeric compositions.

First claim

The invention claimed is:

1. A compound of the following formula (I):

wherein n and p are identical and independently represent an integer from 3 to 12 and m represents (n−2).

2. The compound according to claim 1 wherein n, m and p are even integers.

3. The compound according to claim 1 , wherein m represents 2 or 3.

4. A method for preparing a compound according to claim 1 , comprising a step consisting of coupling a compound having the following formula (II):

wherein m and p are as defined in claim 1 ,
with a dialcohol of the following formula (III):
HO—(CH 2 ) n —OH  (III),

wherein n is as defined in claim 1 .

5. A method for preparing a (PEA) polymer comprising a step consisting of heating to a temperature greater than or equal to the melting temperature of the compound of formula (I) and under reduced pressure, a compound of formula (I) according to claim 1 , in the presence of a catalyst, in order to polymerize said compound of formula (I).

6. The method for preparing a (PEA) polymer according to claim 5 , wherein the compound of formula (I) is brought into contact with a compound of the following formula (IV):

wherein n is as defined in claim 1 and R″ represents H or an alkyl with 1 to 5 carbon atoms.

7. The method for preparing a (PEA) polymer according to claim 5 , wherein the compound of formula (I) is the compound according to claim 4 .

8. A (PEA) polymer comprising subunits derived from succinic acid, 1,4-butanediol and 1,4-butanediamine and being obtainable by a method comprising a step consisting of heating a compound of formula (I) according to claim 1 wherein n and p represent 4 and m represents 2 to a temperature greater than or equal to the melting temperature of said compound of formula (I) and under reduced pressure, in the presence of a catalyst, in order to polymerize said compound of formula (I).

9. A method for improving the heat resistance of a composition, comprising the step of adding to said composition a (PEA) polymer according to claim 8 .

10. A composition comprising:
a (PEA) polymer according to claim 8 .

11. A composition according to claim 10 , comprising at least one other polymer (P), and/or natural fibers.

12. The method for preparing a (PEA) polymer according to claim 6 , wherein the compound of formula (I) is brought into contact with a compound of the following formula (III):

wherein n is as defined in claim 1 .

13. A plastic article comprising a composition according to claim 11 .

14. A (PEA) polymer comprising subunits derived from glutaric acid, 1,5-pentanediol and 1,5-pentanediamine and being obtainable by a method comprising a step consisting of heating a compound of formula (I) according to claim 1 wherein n and p represent 5 and m represents 3 to a temperature greater than or equal to the melting temperature of said compound of formula (I) and under reduced pressure, in the presence of a catalyst, in order to polymerize said compound of formula (I).

15. A method for improving the heat resistance of a composition, comprising the step of adding to said composition a (PEA) polymer according to claim 14 .

16. A composition comprising a (PEA) polymer according to claim 14 .

17. A composition according to claim 16 , comprising at least one other polymer (P), and/or natural fibers.

18. A plastic article comprising a composition according to claim 17 .
