Terpene
resin, also known as terpene or pinene resin. It is mainly the use of
turpentine a-pinene or β-pinene, in the Fock's catalyst under the action of
cationic polymerization from the liquid to the solid of a series of linear
polymer.
The
α-pinene component, the β-pinene component mixed monomer, the chemical agent
and the catalyst are added to a three-necked flask equipped with a stirrer and
a temperature measuring device in a predetermined order, and then the mixture
is discharged for a period of time according to the set temperature Into the
boiling water to destroy the catalyst to stop the copolymerization of chemical
reactions, while heating uniform mixing. When the reaction temperature of the
system reached 85 ° C, the temperature was not increased, the residue was
separated by filtration, and the filtered solution was allowed to stand for
stratification. The organic phase material was diafiltered with a stratified
segregation funnel and washed with boiling water to a neutral pH. Acid-base
neutral organic compounds filter out chemical reagents and a small amount of
turpentine which does not undergo polymerization at atmospheric pressure, and
then filter out the lower boiling polymer mass under reduced pressure
conditions, and the fraction remains to obtain this Terpene Resin.
