Notes:
It has been demonstrated that the adhesion of high polymers to cellulose is a function of tack temperatures and dielectric constants, ∊, of the polymers and of dipole moments, μ, of polar groups. A plot of tack temperature versus mirror image force, μ1μ2/,of copolymers gives an area of adhesion bounded by a tack temperature of 100% and mirror image forces of 0.7 and 1.3 and opening toward lower tack temperatures. Outside of the area polymers do not adhere well to cellulose. By coating polymers on cellulose pretreated with Werner chromium complexes of acids bearing polar groups, it has been found that adhesion is a specific function of the polar groups within the polymer and on the modilied cellulose. Adhesion is strongest with approximately equal dipole moment substituents on the modified cellulose and in the copolymers.
