Kinetics of the Radical Copolymerization of 2,2,2- Trifluoroethyl methacrylate with tert-Butyl - trifluoromethacrylate

Mini-emulsion preparation, kinetics of reaction and physical properties of acrylic terpolymer lattices

In this study, stable lattices of terpolymer butyl acrylate, methyl methacrylate, and styrene were synthesized by a mini-emulsion polymerization technique using tert-butyl hydroperoxide TBHP/Fe2 /ethylenediaminetetraacetic acid/sodium formaldehyde sulfoxylate redox initiators at room temperature, and the kinetics of the reaction were studied. The reaction rate was obtained from periodic samplin...

Effects of 2,2,2-trifluoroethyl methacrylate on properties of autopolymerized hard direct denture reline resins.

This study evaluated the effects of the fluorinated monomer of 2,2,2-trifluoroethyl methacrylate (TFEMA) on the properties of autopolymerized hard direct denture reline resins. Iso-butyl methacrylate (i-BMA) and 2-hydroxyethyl methacrylate (2-HEMA) containing 30% TFEMA by weight were used as monomers, while poly(ethyl methacrylate) was used as a powder. Setting characteristics, dynamic mechanic...

Denture base polymers, poly methyl methacrylate improved using free radical copolymerization

Poly methyl methacrylate (PMMA) is the most common material used in Prosthodontics. Several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes cross linking or copolymerization. The innovative method for improving the physical properti...

Self-structuring in amphiphilic networks prepared by single conventional radical copolymerization of n- butyl methacrylate and vinylpyrrolidone

Copolymers of vinyl-containing benzoxazine with vinyl monomers as precursors for high performance thermosets.

A benzoxazine containing a vinyl group (P-4va) was prepared by the reaction of phenol, 4-vinylaniline, and paraformaldehyde. A differential scanning calorimetry (DSC) study revealed that ring-opening polymerization of the benzoxazine and chain polymerization of the vinyl group occurred in the same temperature range. When 2,2'-azobisisobutyronitrile was added as a radical initiator to P-4va, how...
