Abstract:
The present invention relates to a biodegradable polyester mixture comprising: i) 71 to 91 wt%, based on the total weight of components i and ii, of a polyester I synthesized from: a-1) 40 to 70 wt%, based on the total weight of components a and b, of an aliphatic C
9 -C
18 dicarboxylic acid or a C
9 -C
18 dicarboxylic acid derivative; b-1) 30 to 60 wt%, based on the total weight of components a and b, of terephthalic acid or a terephthalic acid derivative; c-1) 98 to 100 wt%, based on the total weight of components a and b, of a C
3 -C
6 diol; d-1) 0 to 2 wt%, based on the total weight of components a and b, of an at least trihydric alcohol; e-1) 0 to 2 wt%, based on the total weight of components a to e, of a chain extender; and ii) 9 to 29 wt%, based on the total weight of components i and ii, of a polyester II synthesized from: a-2) 40 to 70 wt%, based on the total weight of components a and b, of an aliphatic C
4 -C
