Extended polymer compositions are provided which comprise polymers containing pendant functional groups of the formula: - R1 - @ - CH2 -X extended, i.e. admixed with, a chalcogenide having the empirical formula R9 - @ - R10 wherein R1 is a divalent organic radical at least 3 atoms in length, X is organoacyl or cyano, A is a chalcogen, each of R9 and R10 is independently selected from hydrogen, NR11R12, NR13 and monovalent organic radicals, at least one of R9 and R10 being NR11R12 or NR13, each of R11 and R12 is independently selected from hydrogen and monovalent organic radicals, and R13 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.
