Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water-soluble reaction products of polyamines and C6 olefin/maleic anhydride copolymers are unsuitable for applications requiring water-insolubility, such as solid carriers for colorants or pharmaceuticals, as they break down upon exposure to water.
Innovation Solution
Development of water-insoluble reaction products formed by reacting polyamine compounds with at least two amine groups and oil-soluble high carbon polar modified polymers, which maintain their structure when exposed to water, serving as carriers or matrices for desired agents like colorants or pharmacologically active agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water-soluble reaction products of polyamines and C6 olefin/maleic anhydride copolymers are used, then ease of operation is improved, but reliability deteriorates because the products break down upon exposure to water
Solution Approach 1:
The patent changes the solubility parameter of the reaction product by using high carbon polar modified polymers (C12-C40) instead of C6 olefin copolymers. This parameter change transforms the product from water-soluble to water-insoluble, resolving the contradiction between ease of operation and reliability by preventing breakdown upon water exposure while maintaining usability.
Solution Approach 2:
The patent creates a composite material system combining polyamines with high carbon polar modified polymers. This composite approach produces a reaction product that integrates both the functional properties of polyamines and the water-insolubility of high carbon polymers, achieving reliability in water environments while preserving operational effectiveness.
2Reliability
If water-insoluble reaction products are developed, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent modifies the manufacturing approach by changing the polymer substrate from C6 olefin to high carbon polar modified polymers (C12-C40). This parameter change in the raw material selection simplifies the manufacturing process for water-insoluble products while ensuring reliability, as the high carbon polymers inherently provide water-insolubility without requiring additional crosslinking or stabilization steps.
