However the slow reaction rates were impractical and solvents were still used in the initial mixing of the polymer with the catalyst 3 10 liu and coworkers recently investigated bulk hydrogenation of diene based polymers via simple. Johannes karl fink in reactive polymers fundamentals and applications second edition 2013. Of the low molecular weight divinyl monomers egdma and dvb are the most effective cross linkers however pendant unreacted vinyl groups remain in the polymer architecture when egdma is used. Same thing happened again.

I just made more clay pendants again and tried the resin and same thing happen again. Therefore pvms represents a unique class of sens that offers the same functions as pdms with the additional ability to tune the chemical nature of the sen via vinyl based reactions. Regular polymers with small pendant groups crystallize more readily than do polymers with large bulky pendant groups. I have made resin pendants successfully and now i made a polymer clay pendant and tried to put resin on it and the resin is not sticking in spots.

Journal of polymer science part a. The oh groups in pva also form strong hydrogen bonds. Pva crystallizes more readily than pvac because of the bulky acetate groups in pvac. I made sure my pendant was clean and tried to apply resin again.
