      Cover: A special reactor setup was developed for the combinatorial anionic polymerization of block copolymers. This is an efficient and reliable approach for the synthesis of block copolymer series with well-defined compositions, enabling detailed comparative studies and tailoring of block copolymer properties. Further details can be found in the article by R. Pettau, C. Erdelen, and H.-W. Schmidt*on page 65.

    1. In-Line Monitoring of Vinyl Chloride Suspension Polymerization with Near-Infrared Spectroscopy, 1 – Analysis of Morphological Properties (pages 11–24)

      João Miguel de Faria Jr., Fabricio Machado, Enrique Luis Lima and José Carlos Pinto

      Monitoring of morphological properties of polymer resins is generally performed through off-line characterization of samples. It is shown here for the first time that it is possible to monitor some morphological characteristics of PVC resins, such as the bulk density, cold plasticizer absorption and average particle diameter, in-line and in real time using near infrared spectroscopy during suspension polymerizations.

    2. Online Monitoring of Polyolefin Particle Growth in Catalytic Olefin Slurry Polymerization by Means of Lasentec Focused Beam Reflectance Measurement (FBRM) and Video Microscopy (PVM) Probes (pages 25–39)

      Unprecedented insight into the particle growth processes during ethylene slurry polymerizations catalyzed by supported single-site and Ziegler catalysts was gained by online monitoring using two different probes inserted directly into the reactor. FBRM online monitoring complemented by PVM online visualization of polymer particles allowed for the distinction of different types of particle growth processes depending on catalyst type and productivity.

    1. Particle Growth During the Polymerisation of Olefins on Supported Catalysts, 1 – Nascent Polymer Structures (pages 40–64)

      In this first part of a two-part review the physical nature of nascent polyolefins produced on supported catalysts is examined. Typical engineering treatment of polyolefin production assumes that nascent polymer (i.e., that made during the fragmentation and initial particle formation steps) has the same physical properties as the polymer produced after several hours and withdrawn from the reactor. This review shows that this is not so, and goes in to discuss how the inherent differences between the nascent and final polymer can have an impact on particle formation and growth.

    1. Design and Implementation of a Reactor Setup for Combinatorial Anionic Synthesis of Block Copolymer Series with Well-Defined Compositions (pages 65–72)

      Robin Pettau, Christian Erdelen and Hans-Werner Schmidt

      Version of Record online: 9 OCT 2009 | DOI: 10.1002/mren.200900037

      A customized reactor setup for the combinatorial anionic synthesis of block copolymer series is presented and its capabilities are demonstrated. The combinatorial approach is of particular benefit for series of block copolymers with identical A-blocks and varying B-blocks.

    2. Design of Optimal Sequential Experiments to Improve Model Predictions from a Polyethylene Molecular Weight Distribution Model (pages 73–85)

      Duncan E. Thompson, Kim B. McAuley and P. James McLellan

      Version of Record online: 12 NOV 2009 | DOI: 10.1002/mren.200900033

      D-, A-, and V-optimal experimental designs are used to select experimental runs to improve predictions in a molecular- weight-distribution model for Ziegler- Natta-catalyzed polyethylene. Novel V-optimal designs techniques are developed to improve the precision of model predictions, and anticipated benefits are quantified. Problems with local minima are discussed and comparisons between the optimality criteria are made.
