Abstract: The invention relates to a hot melt adhesive composition comprising from 5 to 35% by weight of at least one styrene block polymeric component, from 40 to 65% by weight of at least one tackifying resin, from 15 to 40% by weight of at least one plasticizer, from 3 to 15% by weight of at least one polyolefin wax having an enthalpy of crystallization of at least 45 J/g, and from 0 to 5% by weight of at least one stabilizer, based on the total weight of the hot melt adhesive composition. The invention also relates to a process for preparing such a hot melt adhesive composition, to an article comprising such a hot melt adhesive composition and to the use of such a hot melt adhesive composition for adhering a hygiene disposable article on a fabric.

Abstract: The present invention relates to a process for the continuous synthesis of heavy alkyl acrylates by a transesterification reaction using hydrozincite as a heterogeneous catalyst.

Abstract: A hot melt adhesive composition comprises from 22% to 60% by weight of at least one styrene block copolymer (A) (designated “SBC (A)”) and from 0.1% to 5% by weight of at least one wax having a congealing point higher than or equal to 60° C. and a needle penetration at 25° C. lower than or equal to 2 dmm. SBC (A) comprises at least one linear styrene block copolymer (A1); and optionally at least one styrene diblock copolymer (A2). The styrene block copolymer (A) has a styrene content higher than or equal to 38% by weight based on the total weight of SBC (A); and a diblock content ranging from 0% to 10% by weight based on the total weight of SBC (A). The hot melt adhesive composition has a viscosity at 120° C. higher than or equal to 30,000 mPa·s, and a viscosity at 177° C. lower than or equal to 5,000 mPa·s.
