Disclosed are processes for preparing a copolymer, a copolymer prepared by the process, a sulfur-crosslinkable rubber mixture, and the use of the sulfur-crosslinkable rubber mixture for production of motor vehicle tires. In one embodiment, the monomer has the formula: A-S-P, wherein A is a chemical group containing at least one aliphatic double bond, S is a sulfur atom, and P is a protecting group.

Method for the synthesis of a copolymer, copolymer, rubber mixture, and use thereof

A vulcanizate of a rubber mixture for a vehicle tire, the rubber mixture containing at least one filler and 10 to 100 phr of at least one polymer A of the following formula:PS&#x2014;R&#x2014;S&#x2014;R)where S is a sulfur atom, and P is a polymer chain which is obtainable by anionic polymerization of at least one conjugated diene and optionally one or more vinylaromatic compounds and which has optionally been chain end-modified, Ris most preferably C-C-alkyl, Ris preferably selected from H and &#x2014;SiRRRin which R, Rand Rare independently selected from H, C-C-alkyl, C-C-aryl and C-C-aralkyl, and n is an integer selected from 1 to 200, where the &#x2014;S&#x2014;R&#x2014;S&#x2014;Rgroup(s) are bonded to the backbone of the polymer chain P.

RUBBER MIXTURE, VULCANIZATE OF THE RUBBER MIXTURE, AND VEHICLE TIRES

Disclosed are monomers for copolymerization with alkenes, dienes, vinyl compounds, and/or vinylidene compounds, a process for preparing a copolymer, a copolymer prepared by the process, a sulfur-crosslinkable rubber mixture, and the use of the sulfur-crosslinkable rubber mixture for production of motor vehicle tires. In one embodiment, the monomer has the formula A-S&#x2014;P, wherein A is a chemical group containing at least one C&#x2550;C aliphatic double bond, S is a sulfur atom, and P is a protecting group.

Monomer for copolymerization with alkenes, dienes, vinyl compounds and/or vinylidene compounds, method for the synthesis of a copolymer, copolymer, rubber mixture and use thereof

Disclosed are RAFT agents, a method of polymerizing alkenes, dienes, vinyl compounds, and/or vinylidene compounds using at least one RAFT agent, polymers prepared by the methods, sulfur-crosslinkable rubber mixtures prepared by the methods, and motor vehicle tires, cords, belts, or hoses incorporating the sulfur-crosslinkable rubber mixtures. In one embodiment, the RAFT agent has the formula Z&#x2014;C(&#x2550;S)&#x2014;S&#x2014;R&#x2014;S&#x2014;P or P&#x2014;S&#x2014;Z&#x2014;C(&#x2550;S)&#x2014;S&#x2014;R&#x2014;S&#x2014;P, wherein P is a protecting group, and Z and R are typical RAFT Z and R groups.
