Photodegradation of Polyurethane Foam Obtained from Renewable Resource-Pulp Production Byproducts

Rigid polyurethane foams were obtained from pulp production byproducts. Three different polyols were used-tall oil polyol, lignopolyol and commercially available polyol for comparison. The obtained rigid polyurethane foams underwent photodegradation at 60DEGC temperature and at 0.89 W/m2 intensity of UV light radiation up to 1000 h. Changes in...

Graft-Copolymer-Based Approach to Clear, Durable, and Anti-Smudge Polyurethane Coatings

Requirements for anti-smudge coatings are tough: They should be invisible, thin, repel any possible contaminant while not affecting the desired properties of the substrate, and they should be highly durable. In the journal Angewandte Chemie, Canadian scientists now present a new coating approach based on graft-copolymer micelles embedded in a...
