    Abstract: The new compositions of matter of the present invention comprise compounds having one of the following formulas: ##STR1## wherein: R is hydrogen or methyl;n is 1 to 16;R.sub.1 and R.sub.2 are defined as R.sub.3 and R.sub.4 below or are joined to form a cycloalkyl, cycloalkenyl, aromatic or a heterocyclic ring containing an oxygen, nitrogen or sulfur atom or an alkoxy, amino, carboxyl, halo, hydroxyl, keto or a thiocarboxyl substituted derivative thereof;R.sub.3 and R.sub.4 are independently selected from (A) hydrogen, alkyl, cycloalkyo, alkenyl, cycloalkenyl, aryl, a heterocyclic ring containing an oxygen, nitrogen or sulfur atom, alkoxy, amino, carboxyl, halo, hydroxyl, keto or a thiocarboxyl and (B) substituted derivatives of the alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl and the heterocyclic ring wherein the substitutions are alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, alkoxy, amino, carboxyl, halo, hydroxyl, keto or a thiocarboxyl;W may be a single bond, oxygen, NR.sub.5, or (CR.sub.6 R.sub.7).sub.m, wherein R.sub.5 is hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl or a heterocyclic ring containing an oxygen, nitrogen or sulfur atom or a substituted derivative of alkyl, cycloalkyl, alkenyl, cycloalkenyl or aryl groups wherein the substitutions are alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, alkoxy, amino, carboxyl, halo, hydroxyl, keto or a thiocarboxyl where R.sub.6 and R.sub.7 are defined as R.sub.3 and R.sub.4 above and m is an integer from 1 to 12; andX is hydrogen or a salt-forming cation.Examples of such compositions are mono-iodopropargyl succinates, maleates, itaconates, diglycolates and phthalates. Other compounds include the mono-iodopropargyl esters of anhydrides such as dimethylglutaric anhydride and ethylenediamine tetraacetic dianhydride. They are used in microbiocidal formulations and effective microbiocides.

    Abstract: A process for increasing the direct esterification reaction rate between a diacid and 1,4-butanediol and for directly esterifying greater than 95% of the acid ends of the diacid by mixing in any order the diacid, the 1,4-butanediol and a catalyst compound selected from organo-titanium, organo-tin, and organo-zirconium compounds, to form a reaction mixture wherein the ratio of diol:diacid is at least 2:1 and then reacting the reaction mixture at an average temperature ranging between 190.degree. C. to 200.degree. C. for a period of time no longer than sixty minutes. The same process may be followed substituting ethylene glycol for 1,4-butanediol, provided the catalyst compound is added neat, further provided that the average reaction temperature ranges from 190.degree. C. to 200.degree. C., and also provided that the reaction mixture be reacted for a period of time no longer than seventy minutes. The product resulting from this process may be polycondensed or further treated to form a high molecular weight polymer.

    Abstract: Polyols containing polyether and polyester moieties, based on phthalic acid are described. A phthalic acid derivative is reacted with a polyether polyol to give the novel polyols which are useful not only in polyisocyanurate foams, but also polyurethane foams as well. The phthalic acid derivative may be phthalic acid, phthalic anhydride and an ester of phthalic acid, for example. The polyester polyol is made from an initiator selected from the group consisting of alkanolamines, alkyleneamines, arylamines, sucrose, glycerin, sorbitol, .alpha.-methylglucoside, .beta.-methylglucoside, and mixtures thereof. The polyester polyol may be made by alkoxylating the initiators.
