## Abstract We have developed a one‐step method for preparing nanocomposites based on powdered isotactic polypropylene (__i__‐PP) as a matrix polymer (melt‐flow index (MFI) = 7.2 g 10 min^−1^), oligo(__i__‐PP‐__g__‐MA) (MFI = 35–70 g 10 min^−1^) as a reactive compatibilizer and docecylamine‐surface
## Abstract In this study, 2‐hydroxyethyl methacrylate and __N__‐isopropyl acrylamide was block grafted onto the polypropylene macroporous membrane surface by photo‐induced reversible addition‐fragmentation chain transfer (RAFT) radical polymerization with benzyl dithiobenzoate as the RAFT agent. T
Diffusion coefficients of u.v. absorbing stabilizers in polypropylene can be measured by using u.v. microscopy to reveal the concentration profile of the additive in a thin polymer film over diffusion distances of as little as 50 #m. The method is more rapid than conventional methods and is illustra
