Abstract
Official abstract text for this publication.
Disclosed are a modified conjugated diene polymer and a method for preparing the same. Provided are advantageously a modified conjugated diene polymer and a method for preparing the same which provide superior compatibility with an inorganic filler, heat generation, tensile strength and abrasion resistance, low fuel consumption and excellent resistance on wet roads.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a modified conjugated diene polymer comprising: (a) polymerizing a conjugated diene monomer, or a conjugated diene monomer and an aromatic vinyl monomer in the presence of a solvent using an organometallic compound to prepare an active polymer having a metal end group; and (b) adding a compound represented by the following Formula 2 to the active polymer to modify the active polymer: wherein R 1 is an alkyl group or an alkylsilyl group, R 2 and R 3 are an alkyl group, a is an integer of 1 to 3, and n is an integer of 0 to 2, wherein two R 1 bonded to nitrogen are identical or different when n is 2, and corresponding groups are identical or different when 3-n is 2 or more. 2. The method according to claim 1 , wherein the organometallic compound is used in an amount of 0.01 to 10 mmol, based on 100 g in total of the monomer. 3. The method according to claim 1 , wherein a molar ratio of the organometallic compound to the compound represented by Formula 2 is 1:0.1 to 1:10. 4. The method according to claim 1 , wherein the polymerization (a) further comprises adding a polar additive. 5. The method according to claim 4 , wherein the polar additive is added in an amount of 0.001 to 10 g, based on 1 mmol in total of the organometallic compound.
