Problems solved by technology

However, some of these ethylene unit-rich diene copolymers are rigid and impart rigidity to the rubber composition, which may prove too high for certain applications, such as in tires

Embodiment Construction

[0021] I. Detailed Description of the Invention

[0022] Any numerical interval denoted by the expression "between a and b" denotes a numerical range greater than "a" and less than "b" (i.e. excluding the limits a and b), while any numerical interval denoted by the expression "a to b" Numerical interval means a numerical range extending from "a" up to "b" (ie, including the strict limits a and b).

[0023] The compounds mentioned in the specification may be of fossil or biobased origin. In the case of biobased sources, they can be produced partly or completely from biomass, or can be obtained from renewable raw materials produced from biomass. Of particular concern are monomers.

[0024] The copolymer according to the invention is essentially characterized as an ethylene / 1,3-butadiene copolymer, which means that the monomer units of the copolymer are those obtained by the polymerization of ethylene and 1,3-butadiene.

[0025] Ethylene units (called UA units) are formed by ...

Abstract

The present invention relates to an ethylene and 1,3-butadiene copolymer containing ethylene units, butadiene units and 1,2-cyclohexanediyl cyclic structural units, and bearing, at one of its chain ends, an alkoxysilyl or silanol function, the functional group F1.

Description

technical field [0001] The present invention relates to ethylene / 1,3-butadiene copolymers comprising 1,2-cyclohexanediyl 6-membered saturated cyclic moieties with alkoxysilyl functional groups at the chain ends or silanol functional groups. Background technique [0002] In order to expand the range of currently available materials and to improve the properties of existing materials, it is always advantageous to have new polymers available. Among the methods used for new polymers, mention may be made of the modification of polymers. [0003] For polymers synthesized by anionic polymerization, modifications are widely described to provide alkoxysilyl functional groups or silanol functional groups at one chain end of the polymer. The modification of the polymer chain ends by anionic polymerization depends on the reactivity of the polymer chains, which is indicated by the absence of transfer and termination reactions during the polymerization. Living polymerization is also ch...
