Abstract:
The present invention relates to innovative amorphous polyurethane polymers of the formula (I) and also to hotmelt adhesive compositions based on them. The compositions are notable for greatly improved dimensional stability after application, and are ideally suited to the adhesive bonding of transparent substrates. The polymers are notable for rapid, bubble-free curing.
