Independent luxury : the four innovation strategies to endure in the consolidation jungle
\"There is an endangered species in luxury: independent companies! In an ever-challenging globalized luxury environment, difficulties arise for companies striving to escape the ever-growing clout of luxury conglomerates. But so do opportunities! Through case studies of game-changing brands including: W Motors, HYT watches, Iris Van Herpen, Comme des Garًcons, Brunello Cuccinelli, Etudes Studio, Holition, Digital Luxury Group, and many others, this book introduces the luxury innovation framework presenting four winning strategies and a unique approach for entrepreneurs, creators, designers, and managers daring to challenge the status quo and to become ground breakers. \"-- Provided by publisher.

Photopolymerizable monomers based on monoglycerides were prepared by a convenient two-step procedure. The first one consists of the synthesis of highly pure monoglycerides by an organocatalyzed solvent-free route. This process was carried out by condensation of bio-sourced carboxylic acids (i.e. butyric, decanoic, undecylenic or stearic acids) with glycerol carbonate or glycidol in the presence of a quaternary ammonium salt as a catalyst. The obtained bio-based monoglycerides were modified in the second step by reaction with acryloyl and methacryloyl chloride leading to a series of new diacrylated and dimethacrylated monomers. The structures of the monoglycerides, diacrylated and dimethacrylated monomers were fully characterized by spectroscopic methods. Photopolymerization investigations monitored by infrared spectroscopy were achieved under ultraviolet radiation in the presence of a photoinitiator. The resulting cross-linked materials were analyzed by thermal gravimetric analysis, gel content determination and tests of swelling in water, ethanol and methylene chloride. Data relative to the pendulum hardness of these materials are also included.
