    摘要: A two-part initiator system useful in acrylic adhesive compositions comprising in one part a stable organoboron amine complex and in the second part an aldehyde destabilizer or activator. This initiator is particularly useful in elastomeric acrylic adhesive compositions and provides room temperature, relatively slow curing systems with good adhesive properties making them useful in applications where longer open times are required.

    摘要: A two-part initiator system useful in acrylic adhesive compositions comprising in one-part a stable organoboron amine complex and in the second part an organic acid destabilizer or activator. This initiator is particularly useful in elastomeric acrylic adhesive compositions and provides a fast, room temperature cure with good stability and exhibiting both high tensile strength and high peel strength.

    摘要: A pressure sensitive, hot melt adhesive is prepared by reacting a normally tacky acrylic-based random copolymer containing from 0.5 to 10% by weight of a chelating comonomer with a chelatable transition metal salt. Preferably the adhesives are oven cured for a short time after application. The chelating comonomer is a beta-hydroxypropyl (meth)acrylate ester of an ortho-hydroxy aromatic acid such as 2-hydroxy-3-(2-hydroxy-benzoyloxy)propyl methacrylate. The metallic salt (e.g. zirconium, ferric, cobalt, or aluminum acetylacetonate) contains a metal ion having a valence greater than 1 and a coordination number greater than 2 and an anion capable of forming a volatile by-product. One or more thermally reversible chelate rings incorporating the metal ion are formed thus crosslinking the polymer chains.
