Abstract
Official abstract text for this publication.
The present invention relates to epoxy group-terminated polymers of the formula (I). Said epoxy group-terminated polymers are suited extremely well as impact resistance modifiers, particularly in epoxy resin compositions. They are particularly suited for use in heat-curing epoxy resin adhesives. It has been found that such epoxy resin compositions not only have excellent mechanical properties and high glass transition temperatures, but also above all improved impact resistance properties, both at room temperature and at low temperatures.
First claim
Opening claim text (preview).
The invention claimed is: 1. An epoxide group-terminated polymer of the formula (I) where Y1 is an n-valent radical of a linear or branched polyurethane polymer terminated with isocyanate groups, PU1, after the removal of the n terminal isocyanate groups; Y2 is a radical of an aliphatic, cycloaliphatic, aromatic or araliphatic epoxide containing a primary or…
