Title: Gerald E Manser: Innovator in Thermoplastic Elastomers
Introduction
Gerald E Manser is a notable inventor based in Folsom, CA (US). He has made significant contributions to the field of thermoplastic elastomers, holding a total of 3 patents. His work focuses on developing innovative materials for high-energy compositions, which have applications in various industries.
Latest Patents
One of Gerald's latest patents involves thermoplastic elastomers that feature an alternate crystalline structure. These novel block polymers are designed for use as binders in high-energy compositions such as propellants and explosives. The block polymers possess an ABA structure, where the A blocks are crystalline at temperatures below 60°C, while the B blocks are amorphous at temperatures above -20°C. Both blocks are polyethers formed from monomers of oxetanes and/or tetrahydrofuran. The polymers melt within the range of 60°C to 120°C and exhibit low viscosities above their melting points due to the mutual miscibility of the A and B blocks.
Another significant patent by Gerald focuses on internally plasticized polyethers derived from substituted oxetanes. These elastomeric binders for projectile propellants are composed of cured polyethers containing THF, CYMMO, BMEMO, BEEMO, and/or OMMO mer units. The polyethers remain fluid at room temperature and are miscible with nitrate ester plasticizers. Propellant binders created from these polyethers are curable, possess low glass transition temperatures, and demonstrate good mechanical properties, with specific impulse values comparable to PEG-based binders.
