Abstract

The invention proposes the following method of producing reactive melts which are especially useful as hotmelt adhesives:

a) suitable meltable hydroxy functional or amino functional polymers or polymer mixes (A) which become liquid at temperatures above 40°C are inhomogenously mixed with b) powdered, solid, surface desactivated polyisocyanates (B) or a suspension of such polyisocyanates (B) in a low volatility carrier fluid, c) in approximately stoichiometric proportions at a temperature of at least 40°C in a static mixer so that the resultant mixture of substances exhibits partial areas in which the ratio (1) of polymer (A) to (2) solid isocyanate (B) and desactivating agent (C) is different from the average ratio of these substances or mixtures thereof within the entire mix, d) the inhomogenous mixture is extracted in a form suitable for the intended use and solidified by cooling to below the mixture's softening point.

These preformed or possibly nonformed solid reactive melts are able to be stored at room temperature and retain their latent thermoreactivity.
