Abstract
A method of manufacturing a modified liquid crystal polymer includes: providing a liquid crystal polymer having a first melting point; heating the liquid crystal polymer to a first temperature and maintaining at the first temperature for a first time period, in which the first temperature is lower than or equal to the first melting point; and cooling the liquid crystal polymer to a second temperature to form a first modified liquid crystal polymer, the second temperature being lower than the first temperature, the first modified liquid crystal polymer having a second melting point, in which the second melting point is higher than the first melting point.

A method of manufacturing a modified crystal polymer, comprising:
- providing a liquid crystal polymer having a first melting point;
- heating the liquid crystal polymer to a first temperature and maintaining at the first temperature for a first time period, wherein the first temperature is lower than or equal to the first melting point;
- and
- cooling the liquid crystal polymer from the first temperature to a second temperature that is lower than 100° C. with a rate ranged from 0.1 to 10° C/min to form a first modified liquid crystal polymer, wherein the second temperature is lower than the first temperature, and the first modified liquid crystal polymer has a melting point range comprising a second melting point that is greater than the first melting point.
A method for changing a melting point of a liquid crystal polymer, comprising:
- providing a liquid crystal polymer having a first melting point;
- heating the liquid crystal polymer to a first temperature and maintaining at the first temperature for 0.5-6 hours, wherein the first temperature is less than or equal to the first melting point;
- and
- cooling the liquid crystal polymer from the first temperature to a second temperature that is lower than 100° C. with a rate ranged from 0.1 to 10° C/min, so that the liquid crystal polymer has a melting point range comprising a second melting point greater than the first melting point, wherein the second temperature is lower than the first temperature.
