Functional Alkyl‐Ferrocene Grafted Hydroxyl Terminated Polybutadiene

ChemistrySelect, 2021
Abstract Grafting of functional ferrocene molecules in the backbone of hydroxyl terminated polybutadiene (HTPB) without altering physical characteristics such as viscosity, hydroxyl value, molecular weight of the pristine HTPB remains as an important challenge owing to the difficulty in synthesizing appropriate functional ferrocene ...

Synthesis of Azide-Functionalized Hydroxyl-Terminated Polybutadiene

Journal of Energetic Materials, 2016
This article reports ways to functionalize hydroxyl-terminated polybutadiene (HTPB) by azide groups to impart energetic properties to the polymer. Two different synthetic approaches were explored to synthesize azide-functionalized hydroxyl-terminated polybutadiene (azide-HTPB).

Effects of thermal ageing on the properties and lifetime prediction of hydroxyl-terminated polybutadiene

open access: yesPolymer, 1994
Abstract Thermal ageing of hydroxyl-terminated polybutadiene propellant binders was carried out at various temperatures between 50 and 100°C. The changes caused by this treatment in properties such as melt viscosity, functional end-groups, molecular weight, tensile strength, elastic modulus and ultimate elongation were examined.

Cleavable polybutadiene rubber: A versatile precursor to hydroxyl-terminated or multi-hydroxyl polybutadiene and polyethylene

Polymer, 2016
Abstract A series of hydroxyl functionalized polybutadienes has been prepared by combining the oxidolysis and reduction of cis-polybutadiene rubber (BR). For the first time, multi-hydroxyl polybutadiene (MHPB) with α,ω- and intrachain hydroxyl groups was synthesized through the simultaneous reduction of –CHO and epoxy groups in epoxidized aldehyde ...

Studies on Hydroxyl Terminated Polybutadiene Toughened Phenolic Resin

High Performance Polymers, 2006
Phenolic novolac was modified with hydroxyl terminated polybutadiene (HTPB) using resole as compatibilizer. These systems were characterized by differential scanning calorimetry, and IR analysis. Neat resin castings were prepared with varying percentages of HTPB.
