IR spectra and structure of polymers of indene and coumarone
The resins were made from the pure monomers, which were made as in [7, 8]. Our specimens of indene andcoumarone hav been described [9].
Massive Preparation of Coumarone
In this work, we report the massive preparation of coumarone-indene resin-based hyper-crosslinked polymers via one-step Friedel-Crafts alkylation. Low-cost coumarone-indene resin serves as the new building block and chloroform is employed as both solvent and external crosslinker.
Comparison on the performance of solid coumarone
Throughout the experiment, solid coumarone-indene resin modified asphalt (S-CMA) and liquid coumarone-indene resin modified asphalt (L-CMA) are prepared by blending solid coumarone-indene resin (S-CIR) and liquid coumarone-indene resin (L-CIR) into the base asphalt (YZ-70#).

Within the vast realm of chemistry, active hydrogen in coumarone-indene resin has garnered significant interest among scientists and engineers due to its unique properties and broad application prospects. Coumarone-indene resin is a natural macromolecular compound formed by the polymerization of unsaturated hydrocarbons from petroleum cracking. Its distinctive chemical structure endows it with numerous superior properties, the most notable being its high reactivity and tunability. The presence of active hydrogen enables the resin to be processed into various high-performance materials, such as high-strength carbon fibers, lightweight foamed plastics, and composites with special functions.
The concept of active hydrogen in coumarone-indene resin dates back to the early 20th century, when scientists discovered that the resin releases a substantial amount of active hydrogen under specific conditions. This active hydrogen not only promotes chemical reactions but also imparts new functional characteristics to the resin. Over time, this discovery has gradually been applied in industrial production and scientific research, emerging as an important branch of modern materials science.
The mechanisms of active hydrogen are multifaceted. First, active hydrogen can react with various organic and inorganic substances to produce corresponding products. For example, it can undergo redox reactions with environmental factors such as oxygen and water vapor, altering the surface properties and microstructure of the resin. Additionally, active hydrogen can act as a catalyst to accelerate chemical reactions and improve production efficiency. Furthermore, it exhibits antimicrobial, anticorrosive, and antioxidant properties, expanding the potential applications of coumarone-indene resin.
In practical applications, active hydrogen in coumarone-indene resin has demonstrated immense potential. In the aerospace field, it enhances material strength and heat resistance, making it an ideal structural material. In energy sectors, active hydrogen serves as an efficient energy storage medium, supporting the development and utilization of renewable energy. In environmental protection, it can be used to treat industrial wastewater and exhaust gases, reducing pollution.
active hydrogen in coumarone-indene resin also faces challenges. First, the release of active hydrogen often伴随着副产品的产生（is accompanied by the generation of byproducts）, and effectively controlling and utilizing these byproducts remains an urgent issue. Second, the environmental impact of active hydrogen requires further study and assessment. For instance, whether it contaminates water bodies or poses risks to human health must be addressed.
To overcome these challenges, scientists are actively conducting relevant research. On one hand, improving manufacturing processes can reduce byproduct formation. On the other hand, developing new environmentally friendly materials and technologies can minimize the environmental impact of active hydrogen. Meanwhile, enhanced research on its environmental effects is critical to guiding its safe and effective application across fields.
As a vital chemical resource, active hydrogen in coumarone-indene resin holds promising research and application prospects. By deepening our understanding of its mechanisms and exploring its diverse uses, we have reason to believe that active hydrogen will play an increasingly important role in future scientific and technological advancements. With ongoing research and technological progress, we can better utilize this precious resource to drive sustainable human development.
