Item produced via injection molding

Abstract

The present invention relates to (1) an item produced via injection molding comprising: i) from 50 to 85% by weight of a biodegradable polyester with MVR (190° C., 2.16 kg) to ISO 1133 of from 10 to 100 cm 3 /10 min comprising: a) from 90 to 99.5 mol % of succinic acid; b) from 0.5 to 10 mol % of one or more C 8 -C 20 dicarboxylic acids; and c) from 98 to 102 mol % of 1,3-propanediol or 1,4-butanediol; ii) from 15 to 50% by weight of polylactic acid; iii) from 10 to 50% by weight of at least one or more mineral fillers, where at least one filler is chalk; and (2) processes for producing the abovementioned items.

1 - 6 . (canceled) 
     
     
         7 . An item produced via injection molding comprising:
 i) from 50 to 85% by weight, based on the total weight of components i) to ii), of a biodegradable polyester with MVR (190° C., 2.16 kg) to ISO 1133 of from 10 to 100 cm 3 /10 min comprising:
