Abstract

Abstract UNSATURATED POLYESTER RESINS DERIVED FROM AN UNSATURATED DICARBOXLIC ACID, A LOWER ALKYLENE NEO-GLYCOL AND A COMPONENT OF THE FORMULA -(1,2,3,4,4,5-HEXA(X-)CYCLOPENT-1-EN-3,5-YLENE)- >(1,2,3,4,4,5-HEXA(X-)CYCLOPENTAN-1,2,3,5-TETRAYL)N> -(CH(-COOH)-CH(-COOH))- WHEREIN X IS A HALOGEN AND N IS THE NUMBER OF REPEATING UNITS OF HEXAHALOCYCLOPENTADIENE PRESENT IN THE DIELSALDER ADDUCT FORMS CORROSIVE RESISTANT CONCRETES WHEN CROSS-LINKED IN THE PRESENCE OF AN AGGREGATE, THE CONCRETE TYPE PRODUCTS CONTAIN UP TO 90 PERCENT OF WEIGHT AGGREGATE AND OPTIMALLY FROM 10 TO 40 PERCENT OF THE POLYESTER RESIN. THE CONCRETE PRODUCTS EXHIBIT OUTSTANDING PROPERTIES AS CONSTUCTION MATERIALS FOR USE IN ACID ENVIRONS AND, DEPENDING UPON THE SPECIFIC USE, MAY CONTAIN ADDITIONAL ADJUVANTS SUCH AS DYES, PIGMENTS, ANTI-FOULANT ADDITIVES, BIOCIDAL AGENTS, WAXES AND THE LIKE. CHLOR-ALKALI ELECTROLYTIC CELL PARTS CONSTRUCTED FROM THE PREFERRED RESIN DERIVED FROM THE DIELS-ALDER ADDUCT OF HEXAHALOCYCLOPENTADIENE AND MALEIC ACID OR ANHYDRIDE ARE NOT ATTACKED BY HOT WET CHLORINE OR BRINE OVER EXTENDED PERIODS OF TIME IN COMPARISON TO NORMAL CONCRETE. LIKEWISE, SALINE SOLUTIONS, ACIDIC SEWER CONTENTS AND THE LIKE ARE NOT RELATIVELY CORROSIVE TOWARD THESE CONSTRUCTION MATERIALS.
