<p>The present invention is directed to transparent light-stable, movable composite systems which are composed of i) at least two rigid parts made of transparent, thermoplastic materials which are joined together by ii) at least one flexible connecting member made of transparent, light-stable thermoplastic polyurethane. The present invention is also directed to a process for preparing the transparent, light-stable movable composite systems of the present invention. Composite systems of the present invention are particularly useful in the building and construction industry. Upon being folded, composite systems of the present invention are very compact and, hence, easily transportable. In addition, composite systems of the present invention can be easily and reversibly folded or unfolded.</p> |
