Claims (5)

1. Fremgangsmåde til stabilisering af polymerer indeholdende estergrupper, kendetegnet ved, at carbodiimider med formel (I)
(I), idet R1, R2, R4 og R6 uafhængigt af hinanden er C3-C6-alkyl, og R3 og R5 uafhængigt af hinanden svarer til Ci-C3-alkyl, i flydende form (væskedoseret) i kontinuerlige eller diskontinuerlige processer tilsættes til fremstilling og/eller forarbejdning heraf.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at grupperne R1 til R6 inde i molekylet er ens.
3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at grupperne R1 til R6 er isopropyl.
4. Fremgangsmåde ifølge et eller flere af kravene 1 til 3, kendetegnet ved, at tilsætningen af den flydende carbodiimid sker ved temperaturer på 10 - 35 °C.
5. Fremgangsmåde ifølge et eller flere af kravene 1 til 4, kendetegnet ved, at det i forbindelse med polymererne drejer sig om polyethylenterephthalat (PET), polybutylenterephthalat (PBT), polytrimethylenterephthalat (PTT), termoplastiske polyurethaner (TPU), copolyestere, termoplastiske elastomerer baseret på polyester (TPE-E), polymælkesyre (PLA) og/eller PLA-derivater, polyhydroxyalkanoater (PHA), stivelsesbaserede kunststoffer og/eller polyamider (PA) eller blends heraf.
