Efficient Synthesis of Narrowly Dispersed Brush Polymers via Living Ring-Opening Metathesis Polymerization of Macromonomers [PDF]
, 2009 Various macromonomers (MMs) were efficiently synthesized through the copper-catalyzed “click” coupling of a norbornene moiety to the chain end of poly(methylacrylate), poly(t-butylacrylate), and polystyrene that were prepared using atom transfer radical ...

THE LICENSING DILEMMA: UNDERSTANDING THE DETERMINANTS OF THE RATE OF LICENSING [PDF]
Licensing entails a tradeoff: licensing payments net of transaction costs (revenue effect) have to be balanced against the lower price-cost margin and/or reduced market share that the increased competition (profit dissipation effect) from the licensee ...

Recent progresses in the development of more reliable predictions of average molecular weights and chain-lenght distributions for complex irreversible non-linear polymerizations [PDF]
, 2005 Prediction of the structure of branched polymers is a challenging problem, for which only more or less clumsy mathematical solutions have been made available for a long time in the case of kinetically controlled polymerizations.
