Measuring T g in Ultra-Thin Polymer Films With an Excimer Fluorescence Technique

September 1, 2001
Author(s)
Christopher C. White, Kalman D. Migler, Wen-Li Wu
An excimer fluorescence technique has been applied to the measurement of T g of ultra-thin polystyrene films. This technique utilizes an excimer-forming molecule with fluorescent emission in two wavelength bands. The intensity ratio of these bands is a

Flow Visualization of Polymer Processing Additive Effects

June 1, 2001
Author(s)
Kalman D. Migler, C Lavallee, M P. Dillon, S S. Woods, C L. Gettinger
Flow visualization was used to understand how polymer-processing additives (PPA) eliminate sharkskin in linear low-density polyethylene (LLDPE). A sapphire capillary die was used to image the coating of the PPA onto the die wall. Depth resolved optical

Extrusion Visualization - from Blend Structure to Sharkskin

May 1, 2001
Author(s)
Kalman D. Migler
Over the last five years, we have developed optical technologies for in-line monitoring of extrusion. We review two areas where we have succeeded in uncovering important concepts and phenomena by shedding light on processes that were previously

Editor's Preface

December 1, 2000
Author(s)
Kalman D. Migler, S G. Hatzikiriakos
The work of J.R. Rice has been central to developments in solid mechanics over the last thirty years. This volume collects 21 articles on deformation and fracture in honor of J.R. Rice on the occasion of his 60th birthday. Contributors include students (P

Droplet Vorticity Alignment in Model Polymer Blends

April 1, 2000
Author(s)
Kalman D. Migler
The shear induced deformation of polymeric droplets in an immiscible polymeric matrix reveals that under conditions of high droplet elasticity, the droplets can align in the vorticity direction. We consider the case where the viscosity ratio of the two
