Abstract

The article focuses on the development of a high-efficiency, metal-free catalyst for silane-modified polyurethane (SPUR) applications. It discusses the properties and advantages of SPUR systems in adhesive, sealant, and coating products, highlighting their moisture curability, enhanced mechanical properties, and excellent adhesion. The chemical processes involved in SPUR curing, including hydrolysis and condensation reactions, are explained.

Abstract

The article describes the self-assembly of the mixture of 1,1-dihydroperfluorooctyl (HPFO) end-capped polystyrene (HPFO-PS) and the corresponding HPFO end-capped polybutylmethacrylate (HPFO-PBMA). Transmission electron microscopy shows that 1/1 (w/w) blends of the mixture form block copolymer-like lamellar structures. The authors explain the film of the 1/1 (w/w) blended HPFO end-functionalized polymers was transparent above 340 nm, while the corresponding homopolymers was opaque below 1000 nm.
