Polymer networks based on cyclodextrin and polyethylene glycol were prepared through polyaddition crosslinking using isophorone diisocyanate. The envisaged material properties are the hydrophilic character. specific to PEG and cyclodextrins. and the capacity to encapsulate guest molecules in the cyclodextrin cavity through physical interactions. https://www.roneverhart.com/Dudley-ASA-Thunder-ZN-Hycon-12-52-300-Softballs-4A-068Y/
