Crosslinking versus interdiffusion in two pot one pack acetoacetoxy-amine based binder system
نویسندگان
چکیده
A two-pot-one-pack waterborne crosslinking system is studied by following the and interdiffusion between polymer particles functionalized with acetoacetoxy on one hand polyethyleneimine other. FTIR spectroscopy rheological measurements are used to follow evolution of crosslinking, while pyrene excimer fluorescence analyse chains neighbouring during film formation. Both proceed slowly at room temperature. However, complete after 24 h 60 °C, does not further this TEM images confirm presence a honeycomb structure in final film, produced crosslinked moieties that can act as barrier for particles. Nevertheless, strong films even absence significant interdiffusion, due crosslinks

Amine Transaminases in Multi-Step One-Pot Reactions
Amine transaminases are enzymes that catalyze the mild and selective formation of primary amines, which are useful building blocks for biologically active compounds and natural products. In order to make the production of these kinds of compounds more efficient from both a practical and an environmental point of view, amine transaminases were incorporated into multi-step one-pot reactions. With...

Strengthening of a Polymer Interface: Interdiffusion and Crosslinking
In many industrial processes, pieces of the same polymer material are brought into contact at a temperature above the glass transition. Interdiffusion takes place across the interface and leads to a strengthening of the junction. Often, a crosslinker agent is also added in order to improve the global mechanical properties of the material, as in the formation of latex films from dispersed soluti...
متن کاملInvestigating the Effect of Curing Agent and Casting Temperature on Pot Life of Binder System Based on HTPB
Effect of temperature and curing agent type parameters on rheological behavior of binder system based on Hydroxyl terminated Polybutadiene (HTPB) is important in the aspect of production for medium and large-size grains. In this research, the effect of casting temperature 40, 50 and 60 ºC) and chemical structure of curing agents (TDI, IPDI and HDI) on rheological behavior of a binder system bas...
