Polyethylene glycol 20 M was used as the stationary liquid, the initial temperature was 80°C, the temperature was maintained for 3 minutes, and the temperature was raised to 2 20 at a rate of 15°C per minute. 0, maintain 4 minutes, the temperature of the sample inlet is 230 degrees ...
Content analysisA 10μl sample is injected into the gas chromatograph, which has a thermal conductivity detector. The column is 1m × 6.35mm stainless steel column. The filler is polyethylene glycol 20M (Carbowax compound 20M) 4%, and the carrier is a 40/60 mesh sieved polytetrafluoroethylene...
Chlorinated polyethylene (CPE) has moderate random chlorination. This suppresses crystallinity or rubber. It can be cross-linked with peroxides. The Cl range is from 36% to 42% vs 56.8% for PVC. The properties include good heat, oil, and ozone resistance. It can be used as a plasticizer ...
Here, the commercially attractive polysulfone (PSF) was grafted by poly(polyethylene glycol) methyl ether methacrylate (PEG) side chains to improve the interfacial interaction with zeolitic imidazolate framework-8 (ZIF-8) nanoparticles and the affinity towards C3H6 for enhanced C3H6/C3H8 separation ...
The α-diimine late transition metal catalyst represents a new strategy for the synthesis of atactic polypropylene elastomer. Taking into account the properties of the material, enhancing the molecular weight of polypropylene at an elevated temperature t
Polyethylene is a polar high polymer. It has a greater affinity for conductive substances such as water. Therefore, the resistance is smaller than the non -polyetry of polyolefins, but there is still a high volume yin and breakdown voltage. The polar...

In this paper, the shape memory (SM) effect of dynamically vulcanized ethylene-propylene-diene rubber/polypropylene (DV-EPDM/PP) blends with typical sea-island structure is successfully fabricated by using sodium methacrylate (NaMAA) as compatibilizer and proper programming. The powerful EPDM/PP ...
