Polyethylene (C2H4)n was compressed to pressures between 10 and 30 GPa in a diamond anvil cell (DAC) and laser heated above 2500 K for approximately one second. This resulted in the chemical decomposition of the polymer into carbon and hydrocarbon reaction products. After quenching to ambient te...
(butylene) and methylpentene. All of these olefins are made intopolymers, but by far the most important arepolyethyleneandpolypropylene. The wide array of uses to which these versatile plastics can be applied and the huge quantities in which they are made so overshadow the otherolefinpolymers ...
Through the chemical foaming high-density polyethylene/polypropylene composition, the hardness and the temperature resistance of the high-density polyethylene can be improved, so that the rejection rate of pair twist of finished cables and the soldering tin retraction length can be reduced....

All fractions were blended, and the material was packaged in low-density polyethylene bags and sealed under vacuum and stored in a freezer at 268.15 + 2.0 K until use. 2.3. Determination of moisture content and the particle density Moisture content (H) of A. lappa leaves samples was ...
The string representations of homopolymer repeat units in this work are PSMILES strings. PSMILES strings follow the SMILES24syntax definition but use two stars to indicate the two endpoints of the polymer repeat unit (e.g.,[*]CC[*]for polyethylene). The raw PSMILES syntax is non-unique; ...
