The present invention relates to polyurethane polymers, a process for their preparation and their use as binders for adhesives, coatings or foams.

Polyurethane polymers

The invention relates to an electro-switchable polymer film assembly having a first and a second surface side, comprising at least one pair of electrodes () and a polymer matrix (), wherein structuring particles () can be embedded in the polymer matrix and the polymer matrix or the structuring particles consist of an electro-active polymer, wherein furthermore, the first and/or the second surface sides can be transferred from a plane condition into a structured condition by electric switching of the electro-active polymer.

Electro-switchable polymer film assembly and use thereof

The invention relates to alkoxysilane groups comprising prepolymers and the use thereof as binding agents for sealants. More specifically the invention relates to alkoxysilyl polyurethanes prepared from a polyol having a number-average molecular weight of from greater than 20,000 to 30,000 and an isocyanate alkoxysilane.

Sealants

Prepolymers, which are accessible from formamides of low molecular weight di- or triamines (formamide-terminated low molecular weight compounds) and di- or polyisocyanates, of the general formula (II):X&#x2014;[&#x2014;N(CHO)&#x2014;CO&#x2014;NH&#x2014;R&#x2014;NCO]&#x2003;&#x2003;(II)wherein X represents a linear or branched aliphatic, cycloaliphatic, heterocyclic and/or aromatic structural unit having 2 to 40 carbon atoms, and which is optionally further substituted and/or optionally comprises one or more heteroatoms, wherein Rrepresents an organic radical which may optionally contain one or more heteroatoms and which may further contain one or more additional free isocyanate groups and/or one or more urethane, biuret, carbodiimide, isocyanurate, allophanate, iminooxadiazinedione and/or uretdione structural units, and wherein n&#x2267;2; processes for making the same; compositions containing the same; and uses thereof.
