3 Terms
The following terms and definitions apply to this standard.
3.1 The glass transition temperature
Amorphous or semi-crystalline polymer from a viscous flow state or a high elastic state (rubbery state) to the glass transition (transition or vice versa) is called the glass transition
Variable, i.e., it corresponds to the transition temperature is a glass transition temperature, referred to as the glass transition temperature.
3.2 Softening temperature
Resin softening temperature deformation of.
3.3 Volatile
Easy resin containing some amount of volatile matter.
3.4 Melt Index
At a certain temperature and load, every 10min polymer melt through the quality of the required standards die.
3.5 Intrinsic viscosity
Also known as the limit viscosity, viscosity at infinite dilution or logarithmic viscosity limits.
3.6 Residual monomers
Resin residual unreacted monomers.
3.7 Acid value
The number of milligrams of potassium hydroxide per 1g resin containing an organic acid consumed.
