HOT MELT ADHESIVE Russian patent published in 2018 - IPC C09J153/02 C08L53/02 A61L15/58 B32B37/12 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a hot melt adhesive and a disposable article obtained by using a hot melt adhesive. Hot melt adhesive can be applied at low temperature. Hot melt adhesive comprises thermoplastic block copolymer (A) which is a copolymer of vinyl class aromatic hydrocarbons and conjugated diene compounds. Thermoplastic block copolymer (A) comprises the following components: (A1) and component (A2). (A1) a radial type styrene block copolymer having a styrene content of 35 to 45% by weight, a diblock content of 50 to 90% by weight, and has a viscosity at 25°C of 25% toluene solution of not more than 250 mPa·s. (A2) a triblock type styrene block copolymer.

EFFECT: technical result achieved with the use of the group of inventions is that the hot melt adhesive is excellent in terms of adhesive capacity in wide temperature ranges (10 to 40°C) and excellent in terms of the balance between tack and retention force.
