Abstract
Official abstract text for this publication.
The present invention relates to a composition comprising (i) a crosslinkable synthetic cis-1,4-polydiene having a cis content of at least 95% and a functional group in the terminal position, and (ii) an amphiphilic compound.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A composition comprising: a crosslinkable synthetic cis-1,4-polydiene having a cis content of at least 95% and a functional group in the terminal position, and an amphiphilic compound, wherein the amphiphilic compound is a polar lipid. 2 . The composition of claim 1 , wherein the cis-1,4-polydiene is a cis-1,4-polyisoprene or a cis-1,4-polybutadiene or a mixture of these two polymers; and/or wherein the synthetic cis-1,4-polydiene is obtainable via a polymerization in the presence of a coordination catalyst that comprises a transition metal or a rare earth metal. 3 . The composition of claim 1 , wherein the terminal functional group is a carboxyl or carboxylate group, a hydroxyl group, an amine or ammonium group, an ester group or a cyano group. 4 . The composition of claim 1 , wherein the amphiphilic compound is present in the composition in an amount of not more than 30% by weight. 5 . The composition of claim 1 , additionally comprising a crosslinker, a sulfur, or a peroxide. 6 . The composition of claim 1 , wherein the polar lipid is phospholipid, a glycolipid, or a mixture thereof. 7 . A process for producing the composition of claim 1 , comprising following process steps: producing a cis-1,4-polydiene having a cis content of at least 95% by a polymerization in the presence of a coordination catalyst, attaching a functional group in the terminal position of the cis-1,4-polydiene, and mixing the cis-1,4-polydiene having a functional group in the terminal position with a polar lipid. 8 . An elastomeric composition obtained by crosslinking the composition of claim 1 . 9 . A shaped body comprising the elastomeric composition of claim 8 . 10 . The shaped body of claim 9 , wherein the shaped body is a tire, a medical device or an industrial rubber product.
