    • 专利摘要:
    There is described a thermoplastic, transparent moulding material comprising 1 - 99 per cent by weight of at least one cellulose esterified with one or more aliphatic carboxylic acids and 99 - 1 per cent by weight of an ethylene-vinyl ester copolymer comprising 30 - 98 per cent by weight of built-in vinyl ester. A further thermoplastic moulding material comprises 50 - 98.99 per cent by weight of at least one cellulose esterified with one or more aliphatic carboxylic acids, 1 - 50 per cent by weight of an ethylene-vinyl ester copolymer comprising 60 - 98 per cent by weight of built-in vinyl ester and 0.01 - 20 per cent by weight of a low molecular weight plasticiser, the sum of 1) - 3) adding to 100 per cent by weight. Finally there is also described a moulding material comprising 95 - 70 per cent by weight of at least one cellulose esterified with one or more aliphatic carboxylic acids and 5 - 30 per cent by weight of an ethylene-vinyl acetate copolymer comprising 30 - 98 per cent by weight of built-in vinyl acetate. The moulding materials described can be used for producing shaped articles such as acetate filament, block acetate, safety film bases, electrical insulation films and packaging films.
