Example 13

A reaction vessel (round-bottom flask with stirrer, reflux condenser, water separator, and dropping funnel) was charged under a nitrogen atmosphere at 80° C. with 200.0 g (0.1 mol) of polyetherdiamine (Jeffamine D2000 from Huntsman). Over the course of 10 minutes, with stirring, 18.9 g (0.22 mol) of butyrolactone were added dropwise. The temperature was via 20-minute temperature ramps, by 10° C. in each case, to 200° C. maintained at this temperature for 6 hours. 0.4 g of p-toluenesulfonic acid was added and stirring continued at 250° C. for 6 hours more. Throughout the reaction time, the water of reaction was removed from the reaction mixture by distillation. The end product is a viscous liquid having an amine number of 6.5 mg KOH/g.

The shell-forming isocyanate, a commercial methylene diphenyl diisocyanate (MDI) oligomer, Ongronat^® 2500, and the monomeric IPDI, Desmodur^® I, to be encapsulated, were kindly supplied by BorsodChem (Kazincbarcika, Hungary) and by Covestro AG (Leverkusen, Germany), respectively. The active (hydrogen) H source Jeffamine^® D-2000, a polyetheramine, was supplied by Huntsman (The Woodlands, TX, USA). Regarding the emulsion stabilizers, the gum arabic (GA) was obtained from Fisher Chemical (Porto Salvo, Portugal), the Dabco^® DC193 was purchased from Air Products, Dow Corning (Bristol, PA, USA), and the Polyvinyl alcohol (PVA), (98–99% hydrolyzed, of medium molecular weight (MW), with an average of 57,000 to 66,000 gmol⁻¹) was obtained from Alfa Aesar (Haverhill, MA, USA). All the chemicals were used as received, without further purification.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
