Chemorheology of Unsaturated Polyester

These limitations are overcome by the introduction of styrene that is, styrene is used as cross-linking monomer for unsaturated polyester. 

The reaction scheme between maleic anhydride and propylene glycol is 

Unsaturated polyester is one of the most versatile thermosets in that it is used in the fabrication of a broad range of products, including structural parts of automobiles, building materials, coating materials, electrical parts, appliances, and boat hulls. Consequently, a variety of resin formulations have been developed, depending on specific applications as well as fabrication processes. Unsaturated polyester and

C. This is understandable because the rate of cure reaction is expected to decrease as the temperature is decreased. In other words, variation of rj during cure depends on the cure kinetics of the unsaturated polyester, suggesting that the chemorheology of unsaturated polyester must be related to the degree of cure a. 

Effects of Low-Profile Additive on the Chemorheology of Unsaturated Polyester... 

Rheological properties of mineral-filled and mineral/glass-fibre-filled unsaturated polyester DMCs have been presented by Gandhi and Bums (1976), who found that a simple power law was useful to characterize the chemorheology of both systems (note that limited cure effects during compressional flow are assumed). This work was extended by a series of... 

In this chapter, we present the chemorheology of three very important thermosets, namely, unsaturated polyester, epoxy, and urethane, placing emphasis on the necessity of connecting the rheological behavior of thermosets with the chemical reactions taking...
