Title: The Innovations of Sara Arshad: Pioneering Silylated Polymers

Introduction

Sara Arshad, an accomplished inventor based in West Springfield, MA, has made significant contributions to the field of polymer science. With a total of three patents to her name, she is recognized for her innovative approaches to enhancing the properties of silylated polymers.

Latest Patents

Among her latest patents is the development of moisture curable compositions that include silylated polymers. This invention provides a two-component moisture curable system designed to produce a cured or cross-linked silylated polymer with improved compression set properties. The first formulation of this system incorporates a silylated polymer, water, and filler, while the second formulation includes a curing catalyst comprising at least one Brønsted acid and a moisture scavenger. The resulting cured formulation exhibits a compression set of less than 100%, with some examples demonstrating less than 50% or even less than 15%. This advancement not only facilitates the use of silylated polymers in applications subject to cyclic loads but also significantly enhances product durability.

Another notable patent focuses on low viscosity silyl-terminated polymers. This invention consists of compositions that feature at least one crosslinkable silyl group in each molecule. This crosslinkable silane-terminated polymer is created through a reaction involving a polyol with a nominal functionality of at least 2 and an isocyanate capped hydrosilylated polymer. Additionally, the hydrosilylated polymer is produced from a reaction between a polymer possessing unsaturated groups and alcoholic hydroxyl groups, and a compound possessing hydrogen-silicon bonds and crosslinkable silyl groups.
