<p>The service temperature of hot melt adhesive compositions containing a partially hydrogenated thermoplastic elastomeric block copolymer, a tackifying resin and a mineral hydrocarbon oil is increased by the presence of a low molecular weight polyphenylene ether resin having a viscosity average molecular weight (M<Sub>vis</Sub>) of between 6,000 and 25,000 and a softening point (Tg) of between 170°C and 210°C.</p><p>The improved compositions are preferably used in the preparation of pressure-sensitive adhesive tapes which are used where high service temperatures are required, for example, in paint shops where service temperatures of 110-120°C are desired.</p> |
