发明名称 Polymers and copolymers of high glass transition temperature from hindered phenols
摘要 Polymers and copolymers having high glass transition temperature and which are soluble in organic solvents are produced from highly hindered biphenols, in particular polyetherketones, polyethersulfones, polyesters and polyetherimides, as well as copolymers based on these polymers may be produced for a variety of applications.
