Synthesis of Poly(N-vinyl-2-pyrrolidone-co-methyl methacrylate) by Maghnite-H+ a Non-toxic Catalyst

Bulletin of Chemical Reaction Engineering & Catalysis, 2014
In the present work poly (N-vinyl-2-pyrrolidone-co-methyl methacrylate) copolymers were prepared successfully and cleanly by a one step process via cationic copolymerization of N-vinyl-2-pyrrolidone (NVP) with methyl methacrylate (MMA), in heterogeneous ...

The Influence of Comonomer on Ethylene/α-Olefin Copolymers Prepared Using [Bis(N-(3-tert butylsalicylidene)anilinato)] Titanium (IV) Dichloride Complex

Molecules, 2011
We describe the synthesis of [bis(N-(3-tert-butylsalicylidene)anilinato)] titanium (IV) dichloride (Ti-FI complex) and examine the effects of comonomer (feed concentration and type) on its catalytic performance and properties of the resulting polymers ...

Copolymerization of trialkylvinyltin compounds

Journal of Polymer Science Part A-1: Polymer Chemistry, 1966
AbstractThe polymerizations of trimethylvinyltin (TMSnV) and tributylvinyltin (TBSnV) were carried out with the use of γ‐ray, radical, or ionic initiators. These monomers did not undergo the polymerization by themselves, but they did copolymerize with styrene (St) or methyl methacrylate (MMA) when a radical initiator was used. From the results obtained

Helix‐sense‐selective copolymerization of triphenylmethyl methacrylate with chiral 2‐isopropenyl‐4‐phenyl‐2‐oxazoline [PDF]

, 2019
The asymmetric induction leading to a one‐handed helix was investigated in the anionic and radical copolymerization of triphenylmethyl methacrylate (TrMA) and (S)‐2‐isopropenyl‐4‐phenyl‐2‐oxazoline ((S)‐IPO), and highly isotactic copolymers with a ...

Copolymerization of Hydrophilic and Hydrophobic Monomers in Water Assisted by Cyclodextrins

Nano Select
To facilitate the copolymerization of both hydrophobic and hydrophilic monomers in aqueous media, cyclodextrins (CDs) are introduced to form inclusion complexes with the hydrophobic monomers.
