Patent ID: 11946168
Assignee: BASF SE
Field: Textile and paper machines (Mechanical engineering)
Classification: CPC D  C | IPC C  D

Claim 0:
1. A process for the preparation of a spinnable composition (sC) comprising the step (I) mixing
80 to 99.5% by weight of at least one terephthalate polyester (A),
0.49 to 19.9% by weight of at least one aliphatic-aromatic polyester (B) obtainable by polymerization of at least the following monomers:
(m1) at least one aliphatic 1,ω-diol,
(m2) at least one aliphatic 1,ω-dicarboxylic acid compound, and
(m3) at least one aromatic 1,ω-dicarboxylic acid compound,
0.01 to 3% by weight of at least one oligomer (C) obtainable by polymerization of at least the following monomers:
(o1) at least one vinylic monomer containing no glycidyl group, and
(o2) at least one vinylic monomer containing a glycidyl group, and
0 to 5% by weight of at least one additive (D),
wherein the % by weight are based in each case on the total weight of the components (A), (B), (C) and optionally-(D) mixed in order to obtain the spinnable composition (sC).
