Abstract: 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.

Abstract: 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—R1—S—R2)n 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, R1 is most preferably C1-C8-alkyl, R2 is preferably selected from H and —SiR3R4R5 in which R3, R4 and R5 are independently selected from H, C1-C16-alkyl, C6-C16-aryl and C7-C16-aralkyl, and n is an integer selected from 1 to 200, where the —S—R1—S—R2 group(s) are bonded to the backbone of the polymer chain P.

Abstract: 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—P, wherein A is a chemical group containing at least one C?C aliphatic double bond, S is a sulfur atom, and P is a protecting group.

Abstract: 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—C(?S)—S—R—S—P or P—S—Z—C(?S)—S—R—S—P, wherein P is a protecting group, and Z and R are typical RAFT Z and R groups.
