<p>Reaction product obtained by combining (i) (R<1>O)4Ti with (ii) 2,4-pentanedione and (iii) either (a) at least one (R<2>O)4Ti or (b) at least one R<3>OH wherein R<2> and R<3> differ from R<1> and are each methyl, ethyl, 2-chloroethyl, isopropyl, n-propyl, n-butyl, n-pentyl, 2-pentyl, 3-methylbutyl, 2-methoxyethyl, or methoxyethoxyethyl and the (i) : (ii) mol ratio is in the range between 1 : 1 and 1 : 2. The quantity of (iii) is sufficient, even in the presence of a nucleating agent, to depress the freezing point of the reaction product obtained by combining (i) with (ii). Methods of preparing the reaction product are disclosed.</p> |
