4603

ISURF 4603 describes a new class of functionalization agents that can be introduced to neodymium-catalyzed butadiene polymerizations to improve various properties of the polybutadiene rubber created.

 

Tires are made of natural and synthetic rubber, filler materials (such as carbon black and silica), steel, textiles, and other materials. The synthetic rubber, polybutadiene, is most commonly synthesized through neodymium-catalyzed butadiene polymerizations. ISURF 4603 introduces a new group of functionalization agents to be added to neodymium-catalyzed butadiene polymerizations that result in end-group functionalizations. The functionalization agents attach to polymer chain ends through interactions with an alkyne group, and once attached to the chain ends, interact with the silica filler in tires to improve various properties of the tire, such as wet skid resistance and fuel efficiency.

• Improved properties of the polybutadiene rubber created.

• Improved properties of the rubber lead to benefits when used in tires, such as reduced rolling resistance and better road adhesion.
