Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus
AIChE Journal, EarlyView.Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Comment on "The dielectric relaxation studies on poly(vinyl acetate)" [PDF]
, 1990 It is shown that the abnormality in the relaxation frequency as reported by Nozaki and Mashimo [J. Chem. Phys. 84, 3575 (1986); 87, 2271 (1987)] in the case of poly(vinyl acetate) can be removed by the use of an equation of the type of a critical power ...
