| Abstract: | PPTA Pulp(pulp of phenylene terephthalamid) is one of the differential products of PPTA fiber which is widely used as reinforcements, friction materials, electric insulating paper, thixotrope and so on. The technology of PPTA Pulp preparation has been developed from cutting spinned filament to polymerizing in a definite solvent at low temperature. The process of PPTA Pulp preparation tends to be easy, stable and cheap. In this paper, the technology of PPTA Pulp preparation were reviewed, and the structure, property. developing prospect of PPTA Pulp were introduced in brief. |
