Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new (meth)acrylate monomers and oligomers with increased bio-based content to enhance sustainability without compromising performance, particularly in adhesives, which traditionally use petrol-based raw materials and lack low odor and low vapor pressure characteristics.
Innovation Solution
A bio-based acrylate monomer is produced by reacting bio-based alkyl-2-hydroxy-3-butenoate with (meth)acryloyl chloride or (meth)acrylic acid/anhydride, resulting in compounds with specific structures that offer improved safety, reactivity, and handling properties, suitable for use in various adhesive applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petrol-based raw materials are used to produce (meth)acrylate monomers, then desired physical properties and performance are achieved, but sustainability is compromised
Solution Approach 1:
The patent changes the source parameter of the raw material from petrol-based to bio-based (specifically sugar-based) carbon sources. The process converts sugar into acrylate monomers through biochemical pathways, fundamentally altering the feedstock parameter while maintaining product performance characteristics.
Solution Approach 2:
The patent replaces traditional petrochemical processing mechanisms with biochemical conversion processes. Instead of using catalytic cracking and refining processes, the invention employs enzymatic and microbial conversion of sugar into the desired monomer structures, substituting mechanical/chemical processing with biological systems.
2Reliability
If traditional (meth)acrylate monomers are used, then adhesive performance is maintained, but health and safety on production lines deteriorates due to high odor and vapor pressure
Solution Approach 1:
The patent modifies the molecular structure parameters of the monomer by introducing specific substituents (R1 and R2 groups) that alter physical properties. The structure includes a hydroxyl group and specific alkyl chains that reduce vapor pressure and odor while maintaining polymerization performance and adhesive properties.
3Object-generated harmful factors
If bio-based raw materials are used to increase sustainability, then environmental impact is reduced, but desired physical properties and performance may be compromised
Solution Approach 1:
The patent applies local quality modification by introducing specific functional groups (hydroxyl at position 2, vinyl group at position 3) and alkyl substituents at specific locations in the molecule. This localized structural modification optimizes both the bio-based content and the physical properties, ensuring that the bio-based monomer achieves desired performance characteristics.
