Reactivity of methacrylates in insertion polymerization.
Polymerization of ethylene by complexes [{(P^O)PdMe(L)}] (P^O = κ(2)-(P,O)-2-(2-MeOC(6)H(4))(2)PC(6)H(4)SO(3))) affords homopolyethylene free of any methyl methacrylate (MMA)-derived units, even in the presence of substantial concentrations of MMA. In stoichiometric studies, reactive {(P^O)Pd(Me)L} fragments generated by halide abstraction from [({(P^O)Pd(Me)Cl}μ-Na)(2)] insert MMA in a 1,2- as...
متن کاملThiol-Ene-Methacrylates as Dental Restorative Materials
Thiol-ene systems demonstrate numerous advantageous polymerization properties in regards to rapid curing, high conversion, minimal oxygen inhibition, and reduced shrinkage stress. However, one of the drawbacks of thiol-ene systems is that commercially available monomers are not able to achieve the mechanical properties required for use as dental restorative materials. Methacrylate systems on th...
متن کاملInvestigation on itaconic acid based pH and salt-responsive biopolymeric hydrogels
Hydrogels are water entrapping polymer network with responding to external stimuli (pH, temperature, electric field, chemical environments, etc.) are often denoted to as “intelligent” hydrogels. In this work, an unique pH and salt-responsive polymeric hydrogel was synthesised based on itaconic acid (IA) via condensation followed by free radical polymerization with ethylene glycol with acrylic a...
متن کاملPolymerization of Alkyl Acrylates and Alkyl Methacrylates with Starch
A series of C4-C 12 alkyl acrylates and methacrylates was polymerized with starch by irradiating starch-monomer mixtures with 60CO. Homopolymers were extracted with cyclohexane. The amounts of insoluble versus soluble synthetic polymer in polymerizations run with alkyl acrylates varied less with the chain length of the alkyl substituent than in the polymerizations run with alkyl methacrylates: ...
متن کاملAllergic contact dermatitis in a dental nurse induced by methacrylates.
Allergy to acrylic plastics is rather frequent among doctors and dental technicians. A rare case of allergy to acrylates in a dental nurse (only one reports can be found in the literature) is presented. The patient reacted to eight chemical compounds of the group under study. UV-cured composites used in conservative dentistry for tooth filling was the source of allergy in the case under report.
