2), testing method
Second-order transition temperature: the second-order transition temperature measuring poly (propylene carbonate) based resin composition according to GB/T 19466.2-2004/LSO 11357-2:1999.Heat-up rate is 20 DEG C/min, rises to 100 DEG C from 10 DEG C, repeats twice, gets secondary value.
Infrared: to be scanned up to 4000cm-1 from 650cm-1;
Thermal weight loss: rise to 500 DEG C from room temperature with the heat-up rate of 10 DEG C/min;
Moment of torsion: the torsion-testing software that torque rheometer carries.
Embodiment one:
60g poly (propylene carbonate) based resin composition is joined in torque rheometer, rotating speed 40rpm, mixing 900s at temperature 120 DEG C, measure moment of torsion and thermal weight loss.See the following form (2) and Fig. 1:
Table 2: the moment of torsion of poly (propylene carbonate) (PPC) composition under Different adding amount
As can be seen from table (2), the moment of torsion moment of torsion after 900s adding poly (propylene carbonate) (PPC) based resin composition of aliphaticdicarboxylic acid two hydrazides class nucleator significantly improves a lot, when addition is 0.5%, moment of torsion just reaches about 5 times of blank resin, and blank resin has become mobility and viscosity closely liquid owing to degrading after mixing 900s at 120 DEG C, cannot be shaping.And the poly (propylene carbonate) based resin composition adding aliphaticdicarboxylic acid two hydrazides class nucleator is very well shaping, there is very strong thermotolerance, the change of the thermotolerance of poly (propylene carbonate) based resin composition can be found out by the thermal weight loss of Fig. 1.Following instance 2 and 3 is all additive with No.3.
Embodiment two
Join in torque rheometer by 60g poly (propylene carbonate) (PPC) based resin composition (content of No3 is 0.5%), rotating speed 40rpm, temperature is mixing 900s at 120,130,140,150,160 DEG C respectively, determining molecular weight.See the following form 3:
Table 3
| Temperature (DEG C) | Mw |
| 120 | 523543 |
| 130 | 474088 |
| 140 | 493243 |
| 150 | 262874 |
| 160 | 213924 |
Poly (propylene carbonate) (PPC) based resin composition adding aliphaticdicarboxylic acid two hydrazides class nucleator has higher thermotolerance, molecular weight changes not quite below 140 DEG C, be still solid-state after mixing, forming, and blank resin is dynamic in viscous flow after mixing 900s, degraded is very severe.
Embodiment three
By 60g poly (propylene carbonate) (PPC) based resin composition (No3 addition is respectively 0.5% and 1%) at 130 DEG C, rotating speed is mixing 900s under 40rpm, measures its molecular weight and second-order transition temperature, in table 4.Its infrared spectrum is shown in Fig. 2:
Table 4
| Addition | Mw | Tg(℃) |
| 0 | ＜4000 | ＜0 |
| 0.5 | 493362 | 31.04 |
| 1 | 581013 | 33.42 |
As can be seen from table 4 and Fig. 2, poly (propylene carbonate) (PPC) resin degradation not adding aliphaticdicarboxylic acid two hydrazides class nucleator is fairly obvious, and annular lactone 1800cm-1 place in infrared spectrum of generation has and significantly goes out peak.Poly (propylene carbonate) (PPC) resin adding aliphaticdicarboxylic acid two hydrazides class nucleator well inhibits the generation of degraded.
Can obviously be found out by above example, when aliphaticdicarboxylic acid two hydrazides class nucleator addition is very low, poly (propylene carbonate) (PPC) based resin composition just can reach higher thermotolerance and anti-degradation property, is conducive to that poly (propylene carbonate) is resinoid to be applied.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; and other any do under not deviating from spirit of the present invention and principle change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
