A process for producing a polyester or copolymer thereof is disclosed. The process comprises contacting at least one carbonyl compound such as, for example, adipic acid, terephthalic acid, salt thereof, or combinations thereof, in the presence of a catalyst, with an alcohol such as, for example, 1,4-butanediol. The catalyst can comprise a tetraalkyl titanate such as, for example, tetraisopropyl titanate and a phosphorous compound such as, for example, a mixture of butyl phosphate and dibutyl phosphate.
