Whether these morphological variations observed in Hbs that polymerize
lead to changes in oxygen transport and fish metabolism is still to be determined.
Overall, the observed dose, as well as total time needed to fully polymerize
the PAA hydrogel, aligned closely with data reported in the literature .
Because this part of the beam is so small, it polymerizes
only the narrowest of swaths of material a time.
(3) Some authors believe that physical proprieties such as hardness and transversal resistance are favored when this process polymerizes
the resins, (4) others believe that the polymerization by immersion in heated water during a long cycle results in better physical properties.
Made of liquid crystal, this template holds the monomers in place while they polymerize
The primary monomer used to polymerize
PEEK (made for Victrex by LaPorte PLC) also faces capacity restraints.
It is comprised of heating to a temperature between 130[degrees]C-180[degrees]C a mixture comprised of one or more ethylenically unsaturated monomers; an initiator system comprising a compound selected from the group consisting of persulfates, peroxides, diazos, and combinations thereof; a substantially aprotic solvent system; and maintaining the temperature of the mixture for a time sufficient to polymerize
the monomers to a monomer to polymer conversion percentage of at least 95% by weight, wherein the polymer has a weight average molecular weight between approximately 900 and 7,000 Dalton, a hydroxyl number of at least 240 and an acid number greater than 240.
When the fibers absorb dilute solutions of the monomers pyrrole or aniline, monomer concentration increases at the fiber surface, where the monomers polymerize
into a thin film.
He explains that these oxidation products start to polymerize
, forming polar molecules that stick to the metal surfaces of servo valves and other hydraulic components.
Plasmas of monomers like ethylene can polymerize
and coat a plastic surface with a dense PE film.
"People have been eager to find alternatives[to cyanoacrylates], particularly for larger-size corneal perforations, where the fluid inside the eye is gushing outside and you can never get it dry enough for the cyanoacrylate to polymerize
,' says Robin, who is at the University of Illinois at Chicago.
The process entails selecting cyclic prepolymers from the group consisting of polyester, polycarbonate and polyurethane; applying the cyclic prepolymers to a surface by a thermal spray or a spray method which uses heat of thermal deposition; ringbreaking the cyclic prepolymers with a catalyst or heat to polymerize
the cyclic prepolymers, while substantially avoiding the evolution of organic content; and heat curing the cyclic prepolymers to complete polymerization of the cyclic prepolymers to form a coating on the surface.
