Hot-melt adhesive

FIELD: chemistry.

SUBSTANCE: invention relates to hot-melt adhesive, particularly to an adhesive, which is used in production of disposable products. Adhesive contains: (A) propylene homopolymer with melting temperature equal to 100 °C or lower, which can be obtained through polymerisation of propylene using metallocene catalyst; and (B) an ethylene-based copolymer.

EFFECT: hot-melt adhesive is suitable for high-speed application and spiral application at low temperature, and also has excellent adhesion to a polyethylene film and nonwoven web.

FIELD: chemistry.

SUBSTANCE: hot-melt adhesive contains at least one copolymer of ethylene and/or propylene and α-olefin, having 4-20 carbon atoms, which is obtained via metallocene-catalysed polymerisation, at least one adhesive resin, as well as at least one ternary copolymer based on α-olefins having 2-5 carbon atoms, and (meth)acrylic esters, and additives. The ternary copolymer based on α-olefins having 2-5 carbon atoms and (meth)crylic esters contains carboxyl and anhydride groups, built through polymerisation or radical grafting of 0.1-7.5 wt % α,β-unsaturated monomers containing acid groups, or anhydride groups.

EFFECT: adhesive has good adhesion, particularly with plastic, metallic and lacquer surfaces, which remains elastic at low temperature, and exhibits high stability in heat.
