Abstract
The present invention relates to modified polyolefins having a propylene content of at least 50 ma-% and a maximum of 75 ma-%, being determined by means ofC-NMR spectroscopy, and having a poly(ethylene) triad content of a maximum of 2.5 ma-%, being determined by means ofC-NMR spectroscopy, relative to the total detected ethylene content, a melting heat of at least 9 and a maximum of 20 J/g, determined by means of differential calorimetry, and a solubility in xylol at ambient temperature of at least 96 ma-%, and a solubility in THF at ambient temperature of at least 67 ma-%, wherein one or multiple silanes are grafted onto the polymer. The invention further relates to a method for the production of the polyolefins, and to the use thereof, particularly in or as an adhesive.
