The phenomenology of the glass transition is briefly reviewed. Four classes of theories for the transition are discussed: rheological theories that account for the temperature dependence of the viscosity and/or relaxation time τp; kinetic theories that predict the form of the relaxation function Mp; relaxation theories that explain both the form of Mp and the temperature dependence of τp; and phenomenological theories that describe the kinetics of relaxation without reference to a microscopic model.
