Summary: This study aimed to modify the polypropylene (PP) surface by grafting with acrylic acid (AA) monomer, using styrene (ST) and benzoyl peroxide (BPO) as comonomer and initiator, respectively, in toluene solution, for potential application as an automatically latex-coagulating cup. The presence of ST comonomer significantly improved the grafting percentage of AA onto PP sheets (PP-g-P(ST-co-AA)), as well as its ion exchange capacity. The grafted PP with ST/AA monomers exhibited high coagulum performance and coagulation rate of natural rubber latex (NRL).

Summary: In this study, styrene was grafted onto isotactic polypropylene (iPP) chains to modify its crystallization behavior. The presence of styrene grafting segments resulted in higher crystallization temperature and rate, as well as smaller crystal size for iPP. The rigid structure of styrene benzene rings promoted the formation of a relatively ordered structure in iPP, while the grafting segments in the amorphous phase hindered crystal growth, leading to finer crystals.

Summary: A single nanoparticle coating method is reported to form 1 nm polymeric shells with various chemical functional groups and surface charges. Nanosecond thermal energy pulses triggered polymerization in the region only a few nanometers from the surface of magnetic nanoparticles under exposure to alternating magnetic field. Modular coatings with different functional groups and surface charges can be achieved by selecting appropriate monomers.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.
