Vegetable Oil-based Hyperbranched Polyols in Flexible Foams
Novel polyols were synthesized by controlled polymerization of hydroxylated fatty acids from methyl soyate. Polymerization of methyl esters of hydroxy fatty acids gives a hyperbranched (HB) product with different content of hydroxyl groups depending on the degree of conversion. Molecular weights, functionality and hydroxyl equivalent of polyols can be controlled by controlling the degree of con...
متن کاملMicrowave-Assisted Synthesis of Polyols from Rapeseed Oil and Properties of Flexible Polyurethane Foams
The application of raw materials derived from renewable feedstock has given rise to growing interest recently, as it can be exploited for the production of bio-based materials from vegetable oils. Their availability, biodegradability and low prices have been taken into account. In this work, vegetable oil-based polyols as a prospective replacement for petroleum polyols were investigated. A two-...
متن کاملThe Modification of Polyurethane Foams Using New Boroorganic Polyols (II) Polyurethane Foams from Boron-Modified Hydroxypropyl Urea Derivatives
The work focuses on research related to determination of application possibility of new, ecofriendly boroorganic polyols in rigid polyurethane foams production. Polyols were obtained from hydroxypropyl urea derivatives esterified with boric acid and propylene carbonate. The influence of esterification type on properties of polyols and next on polyurethane foams properties was determined. Nitrog...
متن کاملDupont’s Renewably Sourced High Performance Polymers
Renewably sourced, also commonly referred as biobased, materials are an integral part of DuPont’s commitment to sustainable growth. DuPont is a market leader in high performance renewably sourced polymers for engineering applications. These include products based on polyamide, polyester and thermoplastic elastomers and contain between 20 to 100 percent renewable carbon by weight. By tapping inn...
متن کاملPolyurethane Adhesives and Sealants Based on Hydrophobic Polyols
Thermosetting polyurethane polymers are staples of adhesive and sealant formulations used in a variety of industrial applications. Polyurethane materials generally provide reliable service under most application conditions, but the long-term performance and durability of some polyurethanes can be compromised by direct and prolonged contact with bulk water or high ambient humidity. The Dow Chemi...
