The role of acetoacetic groupings in the production of varnish and adhesive sealants.
Part I. The use of acetoacetic groupings in the chemistry of macromolecular compounds
for making varnish and adhesive sealants
Polimery 1999, No 1, 6
Preparation of copolymers involving mers containing acetoacetic side groupings is reviewed. In linear macromolecular compounds crosslinked, such groupings expand the field of applications, especially as regards modern varnishes and adhesive sealants. The chemical courses of crosslinking of polymers and resins containing acetoacetic groupings (Michael reaction, reactions with diamines and diisocyanates, use of enamines) and acetylacetonation of resins with hydroxyl groups (e. g., ofpolyesters) are presented.
Keywords: polymers and resins containing acetoacetic groupings, crosslinking with participation ofacetoacetic groupings, varnish products
