Abstract

Organopolysiloxaneurea polymers with good melt viscosity but which effectively crosslink in the presence of moisture contain alkylalkoxysilane or alkylaminoalkylalkoxysilane groups pendant to the polymer chain. The polymers are useful as non-creeping hot melt adhesives, and for other uses as well.
