The present invention refers to the technical field of polymeric compositions, especially polymeric compositions, compositions to be used in or as adhesives, particularly pressure sensitive adhesives.

TYPE OF DEVELOPMENT

Polymeric compositions

DESCRIPTION

The present invention relates to a method for producing a preferably water-based dispersion, particularly to be used as or in an adhesive, especially a pressure-sensitive adhesive (=PSA), particularly a pressure-sensitive adhesive removable under neutral or basic (alkaline) conditions, as well as to the polymeric composition thus produced and to its various uses, usages and applications.

INDICATION

• Glass recycling industry
• Plastic recycling industry
• Label and packaging materials
• Electronics

NOVELTY/ADVANTAGE

Adhesives used to attach or adhere labels etc. to surfaces should be removable, especially using an economic and environmental-friendly method. No reports about the synthesis of waterbone PSAs with remarkable properties and high bio-content using bio-based ASRs as stabilizers containing isosorbide methacrylate monomers have been found. The present invention allows the one-post synthesis of high performance waterbone PSAs with bio contents ranging from 0% to 71% stabilized with ASR type electrostatic stabilizers promoting excellent removable properties.
