Polypropylene blends with both polybutadiene rubber and polycarboxylbuturonile rubber and the required amount of acrylamide was prepared by blending with water, improve the foaming and thermal properties of polypropylene.

Polypropylene with long chain branching behavior was constructed by lignin, which foaming property and polarity were improved.

Mixed matrix membranes (MMMs) containing fluorescent coordination polymers (CPs) showed high sensitivity and selectivity for detecting Cr₂O₇²⁻ in water. Both recyclability and stability of the MMMs were remarkably higher than those of CP powders.
