While pvms polymers have been known and synthesized for many decades limited in. 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.

I just made more clay pendants again and tried the resin and same thing happen again. Same thing happened again. Leading to the modification of pendant vinyl groups. 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.

Branched polystyrene with abundant pendant vinyl functional groups from asymmetric divinyl monomer. Journal of polymer science part a. 1 16 of 547 results for sculpey clay bulk sculpey s8 original polymer clay 8 pound white. 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.

I made sure my pendant was clean and tried to apply resin again. 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. Poly vinyl alcohol pva is made by the hydrolysis of poly vinyl acetate pvac. The oh groups in pva also form strong hydrogen bonds.

Gilliom reported the first study of the bulk catalytic hydrogenation of c c bonds of diene based polymers. Polymer chemistry 2008 46 18 6023 6034. Unicone art epoxy resin kit for art and jewelry making clear casting liquid 1 gallon set 4 5 out of 5 stars 408. A siloxane polymer with pendant epoxide rings on the side chain of the polysiloxane polymer backbone when blended with diglycidyl bisphenol a ether and cured increases the mobility of the crosslinked network and the thermal stability.

Pva crystallizes more readily than pvac because of the bulky acetate groups in pvac.
