ABSTRACT:
Extended polymer compositions are provided which comprise polymers containing pendant functional groups of the formula: ##STR1## extended, i.e. admixed with a chalcogenide having the empirical formula ##STR2## wherein R.sub.1 is a divalent organic radical at least 3 atoms in length, X is organoacyl or cyano, A is a chalcogen, each of R.sub.9 and R.sub.10 is independently selected from hydrogen, NR.sub.11 R.sub.12, NR.sub.13 and monovalent organic radicals, at least one of R.sub.9 and R.sub.10 being NR.sub.11 R.sub.12 or NR.sub.13, each of R.sub.11 and R.sub.12 is independently selected from hydrogen and monovalent organic radicals, and R.sub.13 is a divalent organic radical. These compositions can be extended with significant proportions of the described chalcogenides with corresponding reductions in polymer concentration without significant loss of physical properties. The resulting combinations are particularly useful as binders and coatings.
