We offer 1H and 13C NMR as a routine service for polymer structural characterization. Examples are shown for polyethyleneglycol (PEG) and polypropylene glycol (PPG), homo or hetero polymers heavily used across chemical, oil and gas, and drug manufacturing industries. We have the NMR methods ready to quantify average chain length and molecular weight of your polymers by a combination of 13C, 1H, and 1H-diffusion NMR.
Similarly, Calixarene molecules are manufactured for applications in drug delivery and also in oil recovery from the ground. There is a wide range of usage for these kind of polymers. However, making circular calixarenes are needed for drug delivery vehicles but linear chains are needed for oil recovery applications. NMR technology is the method of choice for structural characterization of these polymers. We have the methodology in place to quantify circular and linear chain polymers for your application need.
