Latest Patents
Kirsch's latest patents include a process for preparing thermoplastic hydrogen-containing fluoropolymers. This innovative process utilizes cyclopentanes alkyl-substituted with one or more C.sub.1 -C.sub.6 alkyls as chain transfer agents in (co)polymerization reactions. These reactions are carried out at low temperatures, ranging from -30°C to +30°C, to produce high-efficiency transfer agents that are non-toxic and yield alkyl end groups with high thermal stability. Another significant patent involves stabilized halopolymer compositions. This composition contains a halopolymer, such as an ethylene chlorotrifluoroethylene copolymer, combined with an effective stabilizing amount of an ester of a (4-hydroxy-5-alkylphenyl) alkanoic acid and at least one phosphite. These compositions are particularly useful in wire and cable coating applications due to their stability at high processing temperatures.
