Nitrogen‐containing monomers. II. Reactivity ratios of n‐vinyloxazolidone and N‐vinylpyrrolidone with vinyl monomers

Abstract

The reactivity ratios in the copolymerization of N‐vinyloxazolidone with styrene, methyl methacrylate, decyl methacrylate, vinyl acetate, and vinyl chloride have been determined and the Alfrey‐Price Q and e values calculated. Reactivity ratios in the copolymerization of N‐vinylpyrrolidone with styrene, methyl methacrylate, and vinyl acetate have also been determined and the Q and e values determined. N‐Vinyloxazolidone was found to be similar but less reactive than N‐vinylpyrrolidone as a comonomer; however, the properties of the resultant copolymers differed appreciably.

High Throughput Characterization of Polymer Libraries by Diffuse Reflectance Infrared Spectroscopy

“…These observations cannot be explained by copolymerization kinetics only. From Q‐e scheme it is known that NVP has only moderate copolymerization capability with MMA . The homopolymers of NVP are water soluble and are therefore removed during workup.…”

“…From Q-e scheme it is known that NVP has only moderate copolymerization capability with MMA. [19] The homopolymers of NVP are water soluble and are therefore removed during workup. The other copolymer systems, however, have rather balanced copolymerization kinetics.…”

A novel crosslinker for UV copolymerization of N ‐vinyl pyrrolidone and methacrylates to give hydrogels

“…Its use in incorporating NVP into methacization of N-vinyl pyrrolidone (NVP). 1 Copolyrylate-based formulations for silicone hydrogels merization of NVP with different kinds of vinyl which led to silicone hydrogels with improved surmonomers under heat, or a combination of heat face wettability which was described in a separate and light, had been studied. Normally, they did study.…”

Synthesis and characterization of N‐vinylpyrrolidone‐tert‐butyl methacrylate‐methacrylic acid terpolymers having amino sugar or bioactive amino side compounds

“…Related to that before mentioned, amphiphilic N ‐vinylpyrrolidone‐ tert ‐butyl methacrylate (VP‐TBMA) copolymers possess several properties that make them feasible macromolecular bioactive carrier candidates. VP is a hydrophilic nonionic monomer of interest for the preparation of bioactive copolymers 8–16. TBMA, a hydrophobic monomer, has been selected to prepare amphiphilic graft and block copolymers17, 18 since subsequent hydrolysis of the tert ‐butyl groups leads to block copolymers containing hydrophobic and hydrophilic segments.…”
