The invention relates to novel transglycosylation products and their
preparation. The transglycosylation products according to the invention
are prepared from starch derivatives, such as esters or ethers of starch.
The products are obtained by reacting a starch derivative with an alcohol
in the presence of an acid catalyst. The forming product is separated by
precipitation or by removing any unreacted alcohol by evaporation. In the
products according to the invention the good properties of starch
derivatives, such as the excellent water resistance of esters, are
combined with the versatility of transglycoside products. The products
can be used as adhesives, in which case they are formulated, for example
as hot-melt adhesives, and as comonomers, prepolymers or macroinitiators
in the preparation of polymers.
