Abstract
Permanently flexible and non-tacky coating mastic and caulking compositions contain one or more polymers having a T.sub.g of about -50.degree. C. to about -10.degree. C. and pendant functional groups attached to the polymer backbone of the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano. The mastics and caulks typically have total non-volatile matter concentrations of about 60 to about 90 weight percent of which about 15 to about 75 weight percent comprises the described polymers and about 25 to about 85 weight percent is non-volatile solid matter other than the polymer such as pigments, fillers, etc. The liquid portion of the mastics and caulks may be a polymer solvent, aqueous polymer dispersant, or other material, and the cured compositions exhibit exceptionally good adhesion to architectural structural materials, especially to materials having relatively non-adherent surfaces such as foamed polyurethane roof insulation and smooth surfaced elastomers and plastics.
