    Abstract: Poly(ethylene terephthalate), poly(1,4-cyclohexanedicarboxylate), poly(ethylene isophthalate), poly(ethylene naphthalate), their copolymers with each other and with modifying aliphatic dicarboxylic acids, and substituted glycol repeat unit modifications thereof are produced from prepolymer (oligomer) obtained from the esterification of the acid or acids with ethylene carbonate or substituted ethylenecarbonate in the presence of one or more amines compounds selected from trialkylamines, tetraalkyldiamines, N-alkylated heterocyclic amines, and certain quaternary ammonium salts, employing certain mole ratios of ethylene carbonate and substituted ethylene carbonate to the diacid. The prepolymer is formed in an unusually short time and the final polyester of high I.V. exhibits improvement in such properties as desirable light color and low ether-glycol level.

    Abstract: A polyisophthalate such as poly(ethylene isophthalate) and copolymers thereof having high intrinsic viscosities as well as reduced ring dimer of ethylene isophthalate, and a process for making the same. A protonic acid catalyst is utilized along with intrinsic viscosity modifying agents during preparation of the polyisophthalate. The polymers produced have very high clarity, improved oxygen and carbon dioxide barrier resistance, high glass transition temperature, as well as increased molecular weights. They are thus suitable for use as materials in packaging or forming containers, such as bottles.

    Abstract: Pigmented thermosetting organic solvent solution coating compositions are disclosed which cure to provide improved weather resistance. These coating compositions contain three resin components, as follows:(1) an essentially nonfunctional organic solvent-soluble silicone resin reaction product of a low molecular weight hydroxy functional polyether with an hydroxy or alkoxy-functional organic polysiloxane, said polyether having an average molecular weight in the range of 300 to 4000 and an hydroxy functionality of at least about 3, said polysiloxane being present in an amount of from 8% to 20% of the weight of the three resin components, and said polyether and said polysiloxane being combined in approximately stoichiometric proportions;(2) a reactive organic solvent-soluble essentially linear high molecular weight hydroxy functional polyester constituting the balance of the three resin components; and(3) from 3% to 15% of the three resin components of a heterocyclic aminoplast resin for curing the reactive polyester.Components 1 and 2 are compatible in the solution and at least partially incompatible in a film as the solvent evaporates, so that component 1 can concentrate at the surface to enhance the weather resistance.
