14.4 Rosins, esters or fortified esters, or phenolic resins from above reacted withterpene resins (7.1, 7.2).14.5 Rosin esters as described under PM/REF numbers 84000, 84080, 84210,84240, 84320, 84400.15. Miscellaneous15.1 Modified polybutadiene rubbers, prepared from butadiene (PM 13630) and othersubstances on the Inventory list of Monomers and Additives.15.2 Polychloroprenes based upon request to add details15.3 Silicones based upon fluids or crosslinked elastomers and resins15.4 Terpene-phenol resins prepared by the reaction of phenol (PM 22960) withterpenes listed in the Inventory list of Monomers and Additives such as alphapinene(PM 23470).16. Polyethers16.1 Polyethers prepared by the reaction of ethylene oxide ( PM 17020 ) and/orpropylene oxide ( PM 24010 ) with mono/polyfunctional alcohols ormono/polyfunctional phenols included in the Inventory list of monomers andadditives, such as 1,2-propylene glycol ( PM 23770 ) , p-cresol ( PM 14770 ),Bisphenol A ( PM 13480 ).Functional groups potentially present :Ether, -OH17. Shellac and ketone resinsShellacShellac is the purified form of the secretion of the insect Laccifer Lacca and can beconsidered as a natural condensation product of aleuritic acid and schelloic acid.Also contains wax which can be precipitated and the resin can also be bleached.Ketone ResinKetone resins are formed by the condensation of the cyclic ketones withformaldehyde using an alkali catalyst. This produces methyl cyclohexanones bysubstitution of the alpha-methylenes.18.
