Abstract (en)

[origin: WO9620220A1] Biodegradable thermoplastic starches contain side chains bound by ester groups. The percentage by weight of the side chains equals at least 10 in relation to the molecular weight (numeric mean value Mn) of the biodegradable thermoplastic starches. Global migration is lower than 200 mg/dm<2> when determined in the conditions set by guideline 90/128/EEC.
