Application of flame retardants (FRs) in textiles is crucial to minimize overall fire risk by delaying or suppressing the spread of fire. The use of FRs additives helps to ensure growing demands for reduction of fire hazard caused by highly flammable materials such as textiles and polymers. This paper aims to introduce chemistry and mechanisms as well as review the recent developments in obtaining...
By polycondensation of styrene with furfural obtained new polymer which can be used as a polymeric matrix for introduction ionogenic groups. Methods of the chemical analysis, IR- and mass-spectroscopy confirm structure of obtained polymer. By sulfonation of styrene-furfural polymer obtained and researched the sulfonic acid cation-exchange resin with high chemical and thermal, and mechanical durability.
Space and matter were created in the Big Bang. Since Big Bang, the Universe has been expanding continually by increasing its entropy. The fundamental forces broke their symmetries, making impossible to unify them together. Nevertheless, the symmetry of the Universe has not changed and interestingly will never. By analysing global and local symmetry, this paper will present a hypothesis on the future...
