Results are presented from studies of ageing effects on and concentration dependences for the modulus of isotactic polystyrene/cis-decalin gels. Ageing does not occur in gels formed and aged below 0 degree C. Modulus increases dramatically upon ageing for gels formed and aged at temperatures above 0 degree C. It is also found that formation temperature and ageing do not affect the shape of the modulus-concentration plot, but they do change the magnitude of the modulus. Modulus increases with increasing ageing time and increasing temperature of gel formation.
