Creep behaviors of gel-spun ultra-high molecular weight polyethylene fibers
关键字：gel-spun ultra-high molecular weight polyethylene fibers
The creep behaviors of gel-spun ultra-high molecular weight polyethylene (UHMWPE) fibers were examined over the temperature range from 200C to 600C under different stress from 9.0 to 22 cN/dtex. The plateau strain rate of the ...

Metal-Free Route to Precise Synthesis of Poly(propylene oxide) and Its Blocks with High Activity
关键字：Metal-Free,propylene oxide,High Activity
The fast and living ring-opening polymerization (ROP) of propylene oxide (PO) by metal-free catalysis is reported. By using triethyl borane (TEB) and organic Lewis bases (LBs, e.g.: phosphazene base, amidine and guanidine) as the catalysts, various alkyl alcohols can effectively initiate the ROP of PO, yielding tailor-made poly(propylene oxide)s (PPOs) with high regioregularity, predictable mole...

Structure and properties of UHMWPE fibers gel-spun from high concentration solution
关键字：UHMWPE fibers; high concentration solution; thermal properties; mechanical properties
The general gel-spinning solution concentration for UHMWPE fibers is only about 5-8 wt%, which results in high manufacturing cost of UHMWPE fibers. In this experiment, UHMWPE fiber was gel-spun from 16 wt% UHMWPE solution. The&nbs...
