Embodiment and comparative example
According to mix ratio recorded in table 1, it is compounded each ingredient, using roller kneading machine in 60~120 DEG C, 10 minutes, decompression
Under the conditions of (0.01kg/cm2) under carry out melting mixing, prepare mixture.Then, using plate pressing by obtained mixing
Object is formed as sheet, the resin sheet of 200 μm of thickness of production.
Following evaluations are carried out using obtained resin sheet (uncured object).Result is shown in table 1.
[Exotherm Onset Temperature and exothermic peak temperature]
Resin sheet is stamped into the round of diameter 4mm, makes sample.For the sample, differential scanning calorimetry (DSC) is used
(TA Instrument manufacture, DSC Q2000), is warming up to 300 DEG C from -50 DEG C with 10 DEG C/min, describes DSC curve, from institute
The DSC curve of description reads Exotherm Onset Temperature and exothermic peak temperature.It should be noted that in the second dervative of exotherm
Value draws tangent line to exotherm at a temperature of being zero, the temperature with the intersection point of baseline is read, as Exotherm Onset Temperature.
[ratio of the thermal discharge of exothermic peak temperature ± 30 DEG C]
From the DSC curve of description, the area (area A) and exothermic peak within the temperature range of exothermic peak temperature ± 30 DEG C are found out
Area is overall (area B).Also, according to following formula, calculate the ratio of the thermal discharge of exothermic peak temperature ± 30 DEG C.
The ratio (%) of the thermal discharge of exothermic peak temperature ± 30 DEG C=area B × 100 area A/
[lowest melt viscosity before preservation]
Using measurement of dynamic viscoelasticity device (manufacture of TA Instruments company, ARES), the minimum of resin sheet is measured
Melt viscosity (determination condition: gap 1mm, parallel board diameter 8mm, measurement frequency 0.1Hz, from 50 DEG C to 150 DEG C with 10 DEG C/min
Heating measurement).
[lowest melt viscosity after preservation]
For the resin sheet after being saved at 25 DEG C 4 weeks, with save before same method, measure lowest melt viscosity.
