SYNTHESIS AND CHARACTERIZATION OF FUNCTIONALIZED VINYL COPOLYMERS II: STRUCTURE-MONOMER REACTIVITY RELATIONSHIP IN COPOLYMERS CONTAINING 4-VINYLPYRIDINE MOIETIES

Copolymers containing 4-vinylpyridine as common monomer with tert-butyl acrylate and acrylic acid of different comonomer compositions were synthesized and characterized. Copolymer composition was determined by elemental analysis, from which monomer reactivity ratios (MRR, r) were estimated using str...
