Patent number: 6946523Abstract: In accordance with the present invention, there are provided novel heterobifunctional monomers and users for the same. Invention compounds have many of the properties required by the microelectronics industry, such as, for example, hydrophobicity, high Tg values, low dielectric constant, ionic purity, low coefficient of thermal expansion (CTE), and the like. These properties result in a thermoset that is particularly well suited to high performance applications where typical operating temperatures are often significantly higher than those at which prior art materials were suitable. Invention compounds are particularly ideal for use in the manufacture of electronic components, such as, for example, printed circuit boards, and the like.Type: GrantFiled: July 1, 2003Date of Patent: September 20, 2005Assignee: Henkel CorporationInventors: Stephen M. Dershem, Kevin J. Forrestal, Puwei Liu

Patent number: 6878797Abstract: A process for producing alkali metal polymaleimide salts by alkaline hydrolysis of maleimide polymers prepared by polymerization of maleimide monomers in the presence of a metal oxide and alcohol initiator or a base. In particular, the process produces alkali metal polymaleimide salts with particular ratios of C—N and C—C connected maleimide-derived monomer units which are dependent on the particular initiator used to synthesize the maleimide polymer. The alkali metal polymaleimide salts, which have chelating and anti-scaling properties, are useful as chelating agents and detergent builders and as such are suitable biodegradable replacements for synthetic polymers and sodium polyaspartate.Type: GrantFiled: April 19, 2002Date of Patent: April 12, 2005Assignees: Board of Trustees of Michigan State University, Applied CarboChemicalsInventors: Kris A.
