Chemical processes for manufacturing bisphenol A, allyl chloride, epichlorohydrin and epoxy resins constitute the Epoxy Resin Combine developed and implemented by Polish inventors of the Institute of Heavy Organic Synthesis and cooperating companies. The Company Petro Carbo Chem Synteza SA at Kedzierzyn-Kozle is producing bisphenol A (12 000 t/a), the Company Zaklady Chemiczne Zachem at Bydgoszcz allyl chloride and epichlorohydrin (33 000 t/a) and Company Zaklady Chemiczne Organika-Sarzyna at Nowa Sarzyna epoxy resins (12 000 t/a). The processes developed are competitive in respect to leading world chemical companies. The novelty and advantages of the processes were the basis for successfuly offering bisphenol A licences to six foreign companies, allyl chloride licence to Samsung Fine Chemicals (South Korea) and lately bisphenol A and epoxy resins to Salzgitter Antagenbau (an Iranian customer). For selling the licences, an income of 23.5 million US$ was achieved.
