Disulfide-containing monomers in chain-growth polymerization

Ultra-precise insertion of functional monomers in chain-growth polymerizations

Chain-growth polymerizations are popular methods because they allow synthesis of highmolecular weight polymers in high yields and in short times. However, copolymers prepared by such processes generally exhibit uncontrolled monomer sequences. The controlled radical copolymerization of styrene with N-substituted maleimides is an interesting exception allowing preparation of controlled primary st...

Containing Adhesion Promoting Monomers

Preeious metal alloys bondcd by the adhesive r'esin were thermocycled O, 1,OOO, 2,OOO, or 4,OOO times in water between 4 and 60°C , and tensile bend strengths were measurecl. Debonded metal surfaces after the tensile test were analyzed based on an area of cohcsive failure. Three-way ANOVA revealed that all the three parameters adherend, adhesive rnonemer, and nurnber of thermal cycles exhibited...

Ultra-fast microwave enhanced reversible addition-fragmentation chain transfer (RAFT) polymerization: monomers to polymers in minutes.

Microwave mediated RAFT polymerization leads to ultra-fast polymerizations, whilst keeping excellent control over molecular weights and molecular weight distributions; this is the first example of such a dramatic effect of microwaves on living radical polymerization kinetics, and it shows the potential for chemists to produce very well controlled polymers in a matter of minutes.

Adhesive properties and kinetic polymerization behavior of resins containing adhesion promoting monomers for precious metals.

Adhesion promoting monomers -5-(4-vinylbenzyl)-2-thiobarbituric acid (5VS), 9,10-epithiodecyl methacrylate (EP8MA), 9,10-epithiodecyl 4-vinylbenzoate (EP8VB), and 3,4-epithiobutyl 2,2-bis(methacryloyloxymethyl)propionate (EP2BMA)--were added to the MMA liquid of a MMA-PMMA/TBBO resin. Three dental precious metal alloys were butt-jointed together with the MMA-PMMA/TBBO adhesive resin, and tensil...
