Introduction
Poly(ester-amide) copolymers are considered interesting targets because they combine outstanding thermal and mechanical properties
of polyamides with the biodegradation capacity of aliphatic polyesters.[1,2] However, obtaining an efficient method which involves the use
of organocatalyst and which works efficiently in the ring-opening polymerization (ROP) of both monomers is a challenging task.
In this work, ε-caprolactam and L-lactide have been copolymerized by a ring-opening process in the presence of two catalysts: a) a
Brønsted acid ionic liquid, i.e. 1-(4-sulfobutyl)−3-methylimidazolium hydrogen sulphate (BAIL) and b) a P4-t-Bu phosphazene superbase
(P4).

Methodology
Results and discussion
Conclusions
In conclusion, it was found that the homopolymerization of ε-caprolactam occurred more efficiently in the presence of P4 while the BAIL
was more effective for ROP of L-lactide monomer. Accordingly, at copolymers with high ε-caprolactam content P4 is more favorable that
BAIL while at low ε-Caprolactam the opposite trend is observed. In future, DSC analyses of the copolymers will be carried out to
determine the polymer crystallinity.

When BAIL is used the conversion of L-lactide monomer is much faster than with P4, and on the contrary, ɛ-caprolactam monomer
conversion is much faster with P4 than with BAIL (Figure 1). FTIR spectroscopy successfully represents the carbonyl group of the ester
and the amide of copolymers with BAIL at different copolymer compositions (Figure 2). In 1H NMR spectra the stars indicate the peaks
related to the sequences given by transesterification reactions after ring-opening polymerization of ɛ-caprolactam when the
copolymerization occurs (Figure 3).

  • 1. Introduction Poly(ester-amide) copolymers are considered interesting targets because they combine outstanding thermal and mechanical properties of polyamides with the biodegradation capacity of aliphatic polyesters.[1,2] However, obtaining an efficient method which involves the use of organocatalyst and which works efficiently in the ring-opening polymerization (ROP) of both monomers is a challenging task. In this work, ε-caprolactam and L-lactide have been copolymerized by a ring-opening process in the presence of two catalysts: a) a Brønsted acid ionic liquid, i.e. 1-(4-sulfobutyl)−3-methylimidazolium hydrogen sulphate (BAIL) and b) a P4-t-Bu phosphazene superbase (P4). Preparation of Poly (ε-caprolactam-co-L-lactide) copolymers in bulk using organocatalysis Andere Basterretxea1,3, David Mecerreyes2, Olivier Coulembier 3, Haritz Sardon1 Methodology Results and discussion Conclusions In conclusion, it was found that the homopolymerization of ε-caprolactam occurred more efficiently in the presence of P4 while the BAIL was more effective for ROP of L-lactide monomer. Accordingly, at copolymers with high ε-caprolactam content P4 is more favorable that BAIL while at low ε-Caprolactam the opposite trend is observed. In future, DSC analyses of the copolymers will be carried out to determine the polymer crystallinity. 1 POLYMAT, University of the Basque Country (UPV/EHU), Joxe Mari Korta Center, Avda.

FTIR spectroscopy successfully represents the carbonyl group of the ester and the amide of copolymers with BAIL at different copolymer compositions (Figure 2). In 1H NMR spectra the stars indicate the peaks related to the sequences given by transesterification reactions after ring-opening polymerization of ɛ-caprolactam when the copolymerization occurs (Figure 3).
