Polyether Amide Sticker Adjuvants for Agrochemical Mass Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sticker adjuvants have limited formulation abilities and those based on alkylphenol ethoxylate condensate polymers are restricted in various regions, necessitating the development of alternative adjuvants that effectively adhere active ingredients to plant surfaces without washing off during rain or irrigation.
Innovation Solution
A polyether amide or polyether imide sticker adjuvant formed by reacting a polyether polyamine with a polyfunctional monomer such as a polyacid, di-functional acyl halide, acid anhydride, or their mixtures, which provides enhanced adhesion and resistance to water wash-off, combined with a spreader adjuvant and solvent to create a spreader-sticker adjuvant for agrochemical compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alkylphenol ethoxylate condensate polymers are used as sticker adjuvants, then adhesion performance is improved, but regulatory restrictions and formulation limitations occur
Solution Approach 1:
The patent changes the chemical composition parameters by replacing alkylphenol ethoxylate condensate polymers with polyether polyamine and polyacid components, creating a new chemical system that achieves comparable adhesion without regulatory restrictions while expanding formulation flexibility
Solution Approach 2:
The invention uses composite material formulation by combining polyether polyamine with polyacid components in specific ratios, creating a composite sticker adjuvant system that provides both effective adhesion and improved formulation versatility compared to single-component alternatives
2Reliability
If sticker adjuvants are used to prevent washing off, then mass retention is improved, but water solubility and environmental safety worsen
Solution Approach 1:
The patent modifies the molecular structure parameters of the sticker adjuvant by using polyether polyamine and polyacid components with specific molecular weights and functional groups, achieving a balance between water solubility and adhesion performance that maintains mass retention while improving environmental safety
Solution Approach 2:
The invention employs biodegradable polyether polyamine and polyacid components that provide effective sticker functionality during the crop cycle but break down naturally in the environment, replacing persistent traditional adjuvants with environmentally benign alternatives
