Sigma-Aldrich Enters Licensing Pact with Australia's CSIRO

March 15, 2010

Sigma-Aldrich has entered into a worldwide licensing agreement with Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO) to manufacture and sell Reversible Addition-Fragmentation chain Transfer (RAFT) agents - organic molecules that can be added to polymerization reactions to precisely control molecular weights and structures of polymers.

Under the terms of the agreement, Sigma-Aldrich has the rights to manufacture and sell the RAFT agents worldwide for all research and development applications. The RAFT agents are the latest addition to Sigma-Aldrich''s growing line of polymer science products sold through its Aldrich Materials Science Initiative. RAFT technology is a living radical polymerization process and a powerful method for the synthesis of tailor-made polymers with predetermined molecular weights and highly complex architectures. Such designer polymers can be used to prepare materials with unique properties controlled by their nanometer scale molecular architecture in industries such as biomedical, specialty chemical and personal care.

The RAFT method is applicable to a wide range of monomers and experimental conditions and its utility is reflected in more than 200 patents related to RAFT technology. Sigma-Aldrich will manufacture and distribute the critical components of RAFT polymerization, RAFT agents, to enable companies and research organizations to undertake further research into this groundbreaking technology.
