SAN examples of modulus retention versus temperature C

Shrinkage and coefficient of thermal expansion are in a rather low or average range for a polymer, depending on the ratio of comonomers. The absorption and alteration by moisture exposure are low. 

Poisson s ratio depends on numerous parameters concerning the grade used and its processing, the temperature, the possible reinforcements, the direction of testing with regard to the molecular or reinforcement orientation. 

Neat SAN grades have fair moduli at room temperature involving fair creep moduli, for example  

These results relate to a few grades only and cannot be generalized.
