Polymers Containing a Polyether Carbonate-Containing Block, Preparation Method Thereof and Use of the Polymers as a Tenside

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to novel polymers that are composed of blocks containing hydrocarbons (block A) and polyether carbonate (block B), and which predominantly have AB and ABA structures. These polymers are specifically designed to be used as surfactants (tensides) in cleaning and detergent formulations. Their key feature is a high proportion of AB block structure (at least 80% by weight) and a controlled amount of ABA structure (1.2 – 20% by weight), which leads to improved surfactant properties, such as a higher critical micelle concentration (CMC). Their production process utilizes specific functional starter compounds and catalysts, allowing for a reduced reliance on petroleum-based ingredients by partially substituting with CO2-derived components.

Use CasesContent extracted from patent full text and abstract with AI.

• As surfactants/tensides in laundry detergents and cleaning products to enhance their cleaning efficiency.
• In industrial cleaning applications where stable emulsification and surface activity are needed.
• For drilling fluids in oil and gas industries as additives to improve emulsification and stability.
• As dispersants and lubricants in manufacturing processes, including textile, paper, and cosmetics industries.
• As fuel additives to enhance fuel properties or performance.
• In the formulation of polyurethane materials, where specific block copolymers are desirable.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduced dependency on petroleum-derived ingredients, supporting greener and more sustainable products by using CO2-based polyether carbonate blocks.
• Improved control of surfactant performance, specifically enabling higher critical micelle concentration (CMC), which can lead to better cleaning at higher concentrations and less unwanted micelle formation.
• Potential cost savings and environmental benefits due to the partial replacement of expensive or unsustainable raw materials with CO2.
• Versatile applicability in a wide range of fields, from household detergents to industrial processes and personal care.
• Compatible with existing detergent and cleaner formulations, and can be used alongside traditional surfactants.
