COMPOSITIONS AND PROCESSES FOR IMPROVING PROPERTIES OF FILLERS

摘要

The present invention relates to processes for modifying a filler material comprising treating the filler material with a composition comprising a xyloglucan endotransglycosylase and (a) a polymeric xyloglucan and a functionalized xyloglucan oligomer comprising a chemical group; (b) a polymeric xyloglucan functionalized with a chemical group and a functionalized xyloglucan oligomer comprising a chemical group; (c) a polymeric xyloglucan functionalized with a chemical group and a xyloglucan oligomer; (d) a polymeric xyloglucan and a xyloglucan oligomer; (e) a a polymeric xyloglucan functionalized with a chemical group; (f) a polymeric xyloglucan; (g) a functionalized xyloglucan oligomer comprising a chemical group; or (h) a xyloglucan oligomer; or a composition of (a-h) without a xyloglucan endotransglycosylase, wherein the modified filler material possesses an improved property compared to the unmodified filler material. The present invention also relates to modified filler materials and modified filler materials obtained by such processes.
