Propylene‐ethylene copolymer covalent adaptable networks (PEC CANs) are synthesized via one‐step, radical‐based reactive processing with the use of initiator, dynamic cross‐linkers, and vinyl aromatic additives. The best CAN suppresses over 98% of creep at 100 °C (semicrystalline state) for 10,000 s compared to neat PEC.

Water-accelerated organic transformations [PDF]
Rather than quenching all reactive intermediates and arresting the reaction, the addition of catalytic or stoichiometric (1-10 equiv.) quantities of H2O to organic and organometallic processes can lead to surprisingly beneficial effects on reaction rate,

A Practical Guide to Heterogeneous Catalysis in Hydrocarbon Transformations
A focused overview of the catalytic processing of hydrocarbons to transform them into more valuable compounds is presented. This work is intended to assist BSc, MSc, and PhD students, as well as junior researchers, in selecting and performing appropriate heterogeneous catalytic processes for specific heterogeneous catalytic reactions.

Technology Strategies in the Knowldge Economy. The Licensing Activity of Himont [PDF]
The exchange of technologies and technological knowledge - through joint-ventures, partnerships, licensing, cross-licensing, R&D contracts - and the upsurge of markets for technology are main features of the "knowledge-based" economy.
