What is polymer processing?
chain-growth and step-growth polymerization reactions build polymer chains from monomers.By processing i understand the degradation of these polymers into monomers.
What synthetic polymer gets harder as the number of carbon atoms in the polymer chain increase?
Polyethylene
What is the polymer processing temperature of Polyethylene?
Polythene takes its temperature from its surrounds, as do all substances unless specifically heated or cooled.
How would you expect the intrinsic volume for a polymer in a particular solvent to vary with temperature?
generally, a polymer gets dissolved in a solvent (which implies lower density and higher volume). the higher the temperature, the quicker the process, so to answer: the intrinsic volume for a polymer in a particular solvent increases with the temperature.
Will heating a lithium- polymer cell increase its efficiency?
yes
What do scientists predict that polymer products will increase the use of?
Nuclear energy
What is Tg?
In chemistry, Tg is the glass transition temperature of an amorphous polymer. It is the individual polymer's fixed temperature at which point it either becomes flexible when the actual temperature of it is higher than the Tg, or it becomes rigid, when the actual temperature is lower than its Tg. An amorphous polymer is one whose structure is tangled. Tg is the cause of polymer items breaking. Leave a plastic bucket outside in winter and it can easily break in its rigid state, frozen or not.
What is the shape of a polymer molecule in solution?
The shape a polymer molecule assumes in solution depends on the polymer-solvent combination, the polymer architecture, chemical groups along the backbone of the polymer chain, the polymer molecular weight, the temperature of the solution, the concentration/viscosity of the solution, the prescence of ions and if the solution is in a static or dynamic state e.g. under shear or in an electric field. This shape could be straight or random coil. The volume the shape assumes may be big or small (depending on the above mentioned parameters) and is more commonly referred to as the hydrodynamic volume. The hydrodynamic volume is used to study the molecular weight of polymers using a technique called size exclusion chromatography.
Which synthetic polymer get harder as the number of carbon atoms in the polymer chain increase?
Polyethylene gets harder as the number of carbon atoms increases.
