Title: Innovations by Andrew L Ratermann
Introduction
Andrew L Ratermann is an accomplished inventor based in Indianapolis, IN (US). He has made significant contributions to the field of polymer chemistry, particularly in the development of modified resin compositions. With a total of 2 patents, Ratermann's work focuses on enhancing the properties of thermosetting resins.
Latest Patents
Ratermann's latest patents include innovations in unsaturated polyester-modified flexible polymers for use in molding. This invention relates to thermosetting unsaturated polyester or vinyl ester resin compositions modified with AB or ABA block copolymers. The A blocks are unsaturated polyester while the B blocks are flexible polymers with a glass transition temperature (Tg) of 0 degrees Celsius or lower. The blocks are generally prepared separately and can have various terminal groups such as hydroxyl, carboxyl, amine, or isocyanate groups. These modified resin compositions exhibit higher flexural strain to failure and are tougher than standard resins without modification.
Another notable patent involves polyester-flexible polymer block copolymers. This block copolymer typically has an AB, ABA, or A(BA)n structure, where the A block is an unsaturated polyester and the B block is a flexible polymer. The preferred reaction route involves reacting a mono or dihydroxy terminated flexible polymer with a diisocyanate, which can then be reacted with the polyester. These block copolymers serve as toughening agents and can be utilized to coat fiber structures, which are subsequently incorporated into a polymeric matrix.
