TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The reacting step further comprises adding at least one second polyalkylene glycol dihydroxyterminated reactant. Preferred Components: (IIIa) has a polyphosphite compound of formula (III) or (IV). (IIIa) contains no units of (B1). (IIIa) contains 10-1000 units of (A1). The trifunctional reactant is a triaryl phosphite or triphenyl phosphine. (IIIa) further comprises a synthetic polymer. The synthetic polymer is a polyolefin.    TECHNOLOGY FOCUS - POLYMERS - Preparation (Claimed): Preparation of (IIIa) comprises: either reacting a triphosphite with a limiting molar amount of dihydroxy-terminated reactant with a molar excess of monofunctional chain stopper, adding a base, heating the triphosphite, the dihydroxy-terminated reactant, where the dihydroxy-terminated reactant comprises at least at least one saturated carbocyclic ring and monofunctional chain stopper and base, and isolating the alkylphenol-free phosphite; or reacting (a) at least one alcohol compound of formula (R2a-OH), (b) at least one diol compound of formula (HO-(R7)a-R8-(R9)b-OH); (c) a trifunctional reactant comprising phosphorus moiety, and (d) if unit B is present, at least one polyalkylene glycol compound of formula (H-(O-Y2)m-OH), in the presence of a base.R2a = 1-40C-alkyl or 2-40C-alkenyl (which is optionally interrupted or terminated by 5-10C-cycloalkyl or cycloalkenyl), 2-40C-polyalkylene glycol chain optionally terminated by 1-4C-alkyl or 3-7 membered ring containing -CO-O-group and optionally substituted by 1-20C-alkyl. Preferred Definitions:    R7, R9 = methylene;    R8 = cyclohexyl;    x = 10-1000;    Y3 = polyalkylene glycol having a repeating unit of 5-100, where the polyalkylene glycol is polyethylene glycol and polypropylene glycol; and    Y2 = -CH2CH2- or -CH(CH3)CH2-.    EXAMPLE - 778 grams of Cyclohexane dimethanol, 1775 g of triphenyl phosphite, 1806 g of stearyl alcohol, and 0.3 g of potassium hydroxide were added to a flask and stirred. The mixture was mixed well and heated to 150 degrees C under nitrogen for 1 hour. The pressure was then reduced to 0.3 mm Hg and the temperature was increased to 180 degrees C for 1 hour. The reaction contents were held at 180 degrees C under the vacuum for 2 hours at which point no more phenol was distilling out. The vacuum was then broken by nitrogen to obtain polymeric polyphosphite.
