Biodegradable polyamidoammonium delivery agents
A novel class of biodegradable polyamidoammonium polymers designed as delivery agents with high strength and versatile thermal properties. Derived from sustainable feedstocks, the materials can form cationic complexes in solution or gelled networks and degrade via an internal cleavage mechanism. They support adhesion to both hydrophilic and hydrophobic surfaces and enable rapid curing at mild temperatures for applications involving strong bonding and delivery of sensitive agents.
Overview
A novel class of polyamidoammonium polymers is presented as biodegradable delivery agents. The materials are derived from sustainable sources such as butadiene, CO2, and amine hardeners, with a structure designed to degrade into simpler compounds. This biodegradation mechanism is intended to support environmentally friendly performance.
The polymers are reported to exhibit high strength and versatile thermal properties, functioning across both hydrophilic and hydrophobic surfaces. This surface versatility is positioned for applications that require strong adhesion and rapid curing at mild temperatures.
