| http://www.w3.org/ns/prov#value | - The polymerization is generally carried out at temperatures from about room temperature to about 150 C. lt is generally preferred to initiate the polymerization at relatively low temperatures such as from about 35 to about 85 C and then to increase the temperature to about 90 to about 150 C as the reaction proceeds and preferably after most of the reaction has been completed.
