Synthesis of integral skin microcellular polyurethane elatomers by reacting hydroxyl-terminated aliphatic polyesters with symmetrical diisocyanates, prepolymers of these isocyanates such as derived from p,p'-diphenylmethane diisocyanate and an aliphatic glycol and mixtures thereof, these are polymerized in the presence of an organic blowing agent, and one or more plasticizers such as of the formulae ##STR1## further enhancement of the results is brought about by the presence of catalysts and cell regulating agents, such as dimethylpolysiloxanes; the obtained elastomers are useful, such as for shoe soles and in the manufacture of other products, e.g., vibration dampening devices, floatation devices, gaskets and the like. |

DETAILED DESCRIPTION What is claimed is: 1.
In a process of preparing an integral-skin microcellular polyester base polyurethane elastomer, the improvement comprising reacting a hydroxyl-terminated aliphatic polyester, an isocyanate and/or an isocyanate prepolymer of an aliphatic or an aromatic glycol and/or triol, in the presence of a blowing agent and at least one plasticizer of the following formulae: ##STR10## or mixtures thereof, wherein R may be different for each position and is alkyl of from 1 to 12 carbon atoms, aryl, alkylated aralkyl, wherein the alkyl moieties may be up to 4 carbon atoms, R' may be different in each of the repeating units, and is H or alkyl up to 4 carbon atoms; Z is alkylene of 2 to 10 carbon atoms; arylene and substituted arylene, aralkylene, wherein the alkylene portion thereof is up to 4 carbon atoms; cycloalkylene of 5 to 8 carbon atoms; and x stands for an integer from 1 to 5; ##STR11## or mixtures thereof, wherein R may be different for each position and is alkyl from 1 to 12 carbon atoms; aryl; substituted aryl; aralkyl; alkaryl wherein the "alk" or alkyl portion of each is up to 4 carbon atoms; or cycloalkyl of 5 to 8 carbon atoms in the ring; and R may be different in each repeating unit and is hydrogen or alkyl from 1 to 4 carbon atoms; and x stands for an integer from 2 to 10; ##STR12## or mixtures thereof, wherein R may be different for each of the positions and is alkyl of from 1 to 12 carbon atoms; aryl; substituted aryl; alkaryl wherein the "alk" moiety is up to 4 carbon atoms; cycloalkyl of 5 to 8 carbon atoms in the ring; R' is H, or alkyl from 1 to 4 carbon atoms in the ring; R" and R"' are H, or alkyl from 1 to 4 carbon atoms; and x stands for an integer from 1 to 5; or ##STR13## or mixtures thereof, wherein R may be different for each position and is alkyl from 1 to 12 carbon atoms; arly; substituted aryl; aralkyl or alkaryl wherein the "alk" or alkyl portion of each is up to 4 carbon atoms; cycloalkyl of 5 to 8 carbon atoms in the ring; and R' is H or alkyl or substituted alkyl of up to 4 carbon atoms; and x stands for an integer from 1 to 10
