Abstract
A method for the synthesis of an elastomer comprising the steps of polymerizing conjugated diene monomer in presence of at least one rare earth transition metal catalyst system to generate a polydiene cement; terminating the polydiene cement with a protic organic compound; connecting polymer chains by reacting (1) a compound containing sulfur and a halogen with (2) an alkenyl ether; and adding a product of the reaction to the cement to generate a polydiene rubber.
Claims20
A method for the synthesis of an elastomer comprising the steps of:
- polymerizing conjugated diene monomer to generate a polydiene cement;
- terminating the polydiene cement with a protic organic compound;
- separately reacting (1) a compound containing sulfur and a halogen with (2) an alkenyl ether;
- and
- adding a product of the reaction to the cement to generate a polydiene rubber.
The method of claim 4, wherein the reaction between the S2Cl2 and alkenyl ether is performed at −15° C. to 100° C.
A method for the synthesis of an elastomer comprising the steps of:
- polymerizing conjugated diene monomer to generate a polydiene cement;
- terminating the polydiene cement with a protic organic compound, the polydiene cement being characterized by a first Mooney;
- separately reacting (1) a compound containing sulfur and a halogen with (2) an alkenyl ether;
- and
- adding a product of the reaction to the cement to generate a polydiene rubber, the polydiene being characterized by a second Mooney higher than the first Mooney.
