Unsaturated polyester resin bụ nke a na-ejikarị eme ihe nke resin thermosetting, bụ nke na-abụkarị ngwakọta polymer linear nwere ester bond na njikọ abụọ na-adịghị edozi site na condensation nke unsaturated dicarboxylic acid na diols ma ọ bụ saturated dicarboxylic acid na unsaturated diols. Ọtụtụ mgbe, a na-eme mmeghachi omume condensation polyester na 190-220 ℃ ruo mgbe a na-atụ anya uru acid (ma ọ bụ viscosity). Mgbe emechara mmeghachi omume condensation nke polyester, a na-agbakwunye ụfọdụ monomer vinyl mgbe ọ na-ekpo ọkụ iji kwadebe mmiri mmiri viscous. A na-akpọ ngwọta polymer a resin polyester unsaturated.
