Abstract NOVEL LACTONE-SILICONE BLOCK COPOLYMERS CONTAINING A BLOCK OF AT LEAST TWO SILOXY UNITS: (R''-O-((C(-R2)2)5-COO)C-(CAH2A-O)B-(CO)W-R''")Y-SI(-RX)- O((4-X-Y)/2) AND A BLOCK OF LACTONE UNITS, -(CR22)GCOO- WITH OR WITHOUT UNITS OF THE FORMULA -SO- SUCH AS OXYALKYLENE UNITS OF THE FORMULA, $CAH2AO$, SUCH COPOLYMERS BEING EXEMPLIFEID BY POLYCAPROLACTONE SILOXANES CONTAINING THE SIOLOXY UNIT: (R''-O-((C(-R2)2)5-COO)C-(CAH2A-O)B-(CO)W-R"''-)YSI(-R)X(-O)((4-X-Y)/2) AND NOVEL POLYCAPROLACTONE SILANES HAVING THE FORMULA: (R''-O-((C(-R2)2)G-COO)C-(CNH2N-O)B-(CO)W-R"''-)Y-SI(-R)X-O(4-X-Y)/2 WHEREIN R IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, A MONOVALENT HYDROCARBON GROUP FREE OF ALIPHATIC UNSATURATION AND HAVING 1 TO 18 CARBON ATOMS, AND A DIVALENT ORGANIC, PREFERABLY HYDROCARBON, CONNECTING GROUP FREE OF ALIPHATIC UNSATURATION AND HAVING 2 TO 18, PREFERABLY 2 TO 12, CARBON ATOMS BONDED TO SILICON BY A LINKAGE SELECTED FROM THE CLASS CONSISTING OF SILICON A CARBON BONDS AND SILICON TO OXYGEN TO CARBON BONDS, AT LEAST ONE R BEING A DIVALENT ORGANIC CONNECTING GROUP INTERCONNECTING A SILICONE BLOCK WITH A LACTONE BLOCK, R'' IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, A MONOVALENT HYDROCARBON GROUP FREE OF ALIPHATIC UNSATURATION AND HAVING 1 TO 18 CARBON ATOMS, AND AN ACYL GROUP OF THE FORMULA: R"C(O)- WHEREIN R" IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN AND A MONOVALENT HYDROCARBON GROUP FREE OF ALIPHATIC UNSATURATION AND HAVING 1 TO 18 CARBON ATOMS, R"" IS A DIVALENT HYDROCARBON GROUP FREE OF ALIPHATIC UNSATURATION AND HAVING 2 TO 18 CARBON ATOMS, (OC) IS A CARBONYL GROUPS, THE GROUP (OC)WR"" HAVING 3 TO 18 CARBON ATOMS, R* IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, HALOGEN, MONOVALENT HYDROCARBON FREE OF ALIPHATIC UNSATURATION, ALKOXY AND ARYLOXY GROUPS AND HAVING NO MORE THAN 18 CARBON ATOMS; R2 IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN AND MONOVALENT HYDROCARBON GROUPS FREE OF ALIPHATIC UNSATURATION AND HAVING 1 TO 18 CARBON ATOMS, -DOIS A DIVALENT ORGANIC GROUP DERIVED FROM AN EPOXIDE BY OPENING OF THE OXIRANE RING, W IS AN INTEGER OF 0 TO 1; A IS AN INTEGER OF 2 TO 10; B IS AN INTEGER OF 0 TO ABOUT 100; C IS AN INTEGER OF 1 TO ABOUT 100; D IS AN INTEGER OF 1 TO 3; G IS AN INTEGER OF 5 TO 6; X IS AN INTEGER OF 0 TO 2; Y IS AN INTEGER OF 1 TO 3; Z IS AN INTEGER OF 1 TO 4; AND X+Y IS AN INTEGER OF 1 TO 3. THESE POLYCAPROLACTONE SILICONES ARE EXCEPTIONALLY USEFUL AS FOAM STABILIZING AGENTS, ESPCIALLY IN THE MANUFACTURE OF POLYURETHANE FOAMS. ALSO DISCLOSED AND PROCEDURES FOR MAKING THE POLYCAPROLACTONE SILICONES AND POLYURETHANE FOAMS USING THE POLYCAPROLACTONE SILICONE MATERIALS.
