Title: Innovations of Leo A Vivola

Introduction

Leo A Vivola is an accomplished inventor based in New Kensington, PA. He has made significant contributions to the field of thermoplastic materials, holding a total of 3 patents. His work focuses on methods for creating stock shapes from advanced polymer compositions.

Latest Patents

Vivola's latest patents include a method for making a thermoplastic stock shape. This innovative method involves densifying a composition that includes a liquid crystal polymer with a high crystallization temperature. The process consists of two main steps: first, densifying the composition into a compact, and second, processing the compact at temperatures below the crystallization temperature using a moderate to high strain rate. The liquid crystal polymer used in this method consists essentially of p, p' biphenol, p-hydroxybenzoic acid, and terephthalic acid monomers, marketed under the trademark 'XYDAR'. A preferred embodiment of this method includes heating the compact to temperatures between about 400°F and 650°F, followed by extruding the heated compact through a uniform flow-type die at a strain rate of at least about 2 sec⁻¹. Additionally, his patents disclose thermoplastic stock shapes weighing about four or more pounds, with thicknesses greater than those obtainable through injection molding.
