A resin has a structure defined by Formula (I) ##STR00001## wherein: (a) each R.sub.5 is independently a methylene group (CH.sub.2), or a methylene group substituted with one or more —H, —CH.sub.3, or halogen functionalities; (b) each R.sub.6 is independently a bond or a straight-chain or branched, linear or cyclic, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic group having between 1 and 2 carbon atoms; (c) each X is independently a functionality possessing at least one non-aromatic alkene or alkyne moiety; (d) each Z is independently either H or X; (e) each Z is independently either H or X, and each p is independently an integer from 1-4; (f) each w is independently 0, or an integer greater than or equal to 1, and (i) when w is 0, the bracket region represents a bond and n is 0, or an integer greater than or equal to 1; and (ii) when n is 0, the bracket region represents a bond. The resin is especially well suited for use in a base station, circuit board, server, router, radome or satellite structure, as well as such processes as digital light printing (DLP), continuous liquid interface printing (CLIP), and Stereolithography (SL).

A composition comprising ##STR00001##
In this composition Ar1 is independently selected from the group consisting of: ##STR00002##
and Ar2 is selected from ##STR00003##
Additionally in this composition, R.sub.1, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.11, and R.sub.12 are independently selected from F, Cl, H, unsubstituted or substituted branched alkyls with 1 to 60 carbon atoms, and unsubstituted or substituted linear alkyls with 1 to 60 carbon atoms; and the compositional ratio of x/y ranges from about 1/99 to about 99/1, and n ranges from 1 to 1,000,000.

Disclosed herein is a composite prepared by dispersing silver flakes in a polyvinyl alcohol (PVA), phosphoric acid (H.sub.3PO.sub.4), and poly(3,4-ethyl-ene-dioxythiophene) (PEDOT):poly(styrene sulfonic acid) (PSS) polymer mixture. The polymer blend can provides conductive pathways between the silver flakes, leading to superior electrical properties even at large deformations.
