    摘要: Pressure-sensitive hotmelt adhesive composition based on non-thermoplastic elastomers, obtained bya) preparing, as the preliminary batch, a composition comprising the elastomers and one or more of the following additives such as fillers, anti-ageing agents, plasticizers and tackifier resins in an intensively shearing, intensively cooling mixer and without solvent, the composition having a final temperature of from 100.degree. C. to 160.degree. C.,b) mixing and homogenizing the preliminary batch in a second mixer with one or more of the following additives such as fillers, anti-ageing agents, plasticizers and tackifier resins, without solvent, the composition having a final temperature of from 100.degree. C. to 160.degree. C.,where the total residence time of the composition at temperatures over 100.degree. C. does not exceed a figure of 6 minutes, so that the resulting hotmelt adhesive composition has a viscosity of more than 900 Pa*s, in particular from 900 Pa*s to 1200 Pa*s, at 130.degree. C. and at a shear gradient of 100 s.sup.-1.
