Abstract
The present invention relates to adhesive compositions containing a polychloroprene dispersion containing a tricyclic diterpenecarboxylic acid having at least two conjugated C═C double bonds per molecule. The present invention also relates to a process for preparing these adhesive compositions and to their use as contact adhesives for organic and inorganic substrates.
Claims6
An adhesive composition comprising a polychloroprene dispersion containing a tricyclic diterpenecarboxylic acid having at least two conjugated C═C double bonds per molecule.
A process for preparing an adhesive composition based on a polychloroprene dispersion containing a tricyclic diterpenecarboxylic acid having at least two conjugated C═C double bonds per molecule which comprises reacting by emulsion polymerization chloroprene with from 2 to 20 parts by weight of 2,3-dichlorobutadiene in the presence of from 1 to 10 parts by weight of a tricyclic diterpenecarboxylic acid having at least two conjugated C═C double bonds per molecule as emulsifier, all amounts are based on 100 parts by weight of the monomers.
