摘要:
A functionalized polymer terminated by using an isocyanato alkoxysilane terminating agent. A method of preparing a functionalized polymer comprising the step of contacting a living polymer with an isocyanato alkoxysilane terminating agent.
摘要:
Metallated aminosilane compounds for use as functional initiators in anionic polymerizations and processes for producing an aminosilane-functionalized polymer using the metallated aminosilane compounds to initiate anionic polymerization of at least one type of anionically polymerizable monomer. Preferred use of the metallated aminosilane compounds results in rubber compositions for use in tires comprising an aminosilane functionalized polymer.

A functionalized polymer defined by the formula π-R1-α, where π is a polymer chain, R1 is a bond or a divalent organic group, and α is a sulfur-containing heterocycle.
摘要:
A method of forming a functionalized polymer, the method comprising reacting a living polymer with a compound defined by the formula where R5 includes a monovalent organic group, R6 independently includes a monovalent organic group, each R7 independently includes hydrogen or a monovalent organic group, each R8 independently includes hydrogen or monovalent organic group, R9 includes a monovalent organic group, M is silicon or tin, and x includes an integer from about 2 to about 10, where R5 and R6 may optionally each independently be alkoxy groups, and where R7, R8, and R9 are non-Zerewitinoff organic groups.

Metallated aminosilane compounds for use as functional initiators in anionic polymerizations and processes for producing an aminosilane-functionalized polymer using the metallated aminosilane compounds to initiate anionic polymerization of at least one type of anionically polymerizable monomer. Preferred use of the metallated aminosilane compounds results in rubber compositions for use in tires comprising an aminosilane functionalized polymer. A telechelic polymer may result from use of the metallated aminosilane compound as a functional terminator.
