Reaction-Induced Phase Separation in Poly(vinyl acetate)/ Polyester Blend

Jan-Anders Edvin Maansson, Véronique Michaud, Xavier Bulliard

In blends of unsaturated polyester (UP), poly (vinyl acetate) (PVAc), and styrene, a reaction-induced phase separation occurs upon curing that is due to the crosslinking between styrene and the UP molecules. The evolution of the morphology was observed by ...

Void Formation And Transport During SMC Manufacturing: Effect Of The Glass Fibre Sizing

Jan-Anders Edvin Maansson, Véronique Michaud, Emmanuelle Comte

The present study investigates the origin of voids in sheet molding compounds (SMCs) sheets and their transport during the manufacturing steps. Paste mixing, impregnation, thickening, and molding have been performed with five different SMC sheets, one with ...

Evaporation kinetics of volatile liquids and release kinetics of water from a smectite clay: Comparison between experiments and finite element calculations

Jan-Anders Edvin Maansson, John Christopher Plummer, Pascal Clausen

Numerical calculations of the evaporation kinetics of bulk volatile liquids and of water from smectite clay granules are compared with experimental results. The weight loss of the volatiles is analyzed by thermogravimetry and differential calorimetry. Unde ...

Small strain mechanical properties of latex-based acrylic nanocomposite films

Jan-Anders Edvin Maansson, John Christopher Plummer

A waterborne latex-based technique has been used to prepare acrylic films with laponite contents up to about 25 vol%. The laponite was attached to the surfaces of the latex particles, giving a cellular arrangement of laponite-rich regions at high laponite ...

Low-Stress Hyperbranched Polymer/Silica Nanostructures Produced by UV Curing, Sol/Gel Processing and Nanoimprint Lithography

Jan-Anders Edvin Maansson, Yves Leterrier, Valérie Geiser

Nanocomposite materials based on a HBP and silica are produced using either a dual-cure sol/gel and photopolymerization process or by mixing silica nanoparticles with the HBP. In both cases the conversion of the HBP is independent of composition and obeys ...
