摘要： A process for producing polymer-functionalized filler particles and polymer-functionalized filler particles obtained by this process. The polymer-functionalized filler particles are used as additives for rubber mixtures. The polymers for functionalizing the filler particles are obtained in-situ starting from filler particles having a surface-bound RAFT agent. The binding of silyl-bearing RAFT agents and of Diels-Alder RAFT agents occurs via the R-group and the subsequent RAFT polymerization proceeds via a reactive site of the RAFT agent.

摘要： 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.

摘要： 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.
