Solution Overview
Problem
Current polymerization methods for polyethers, polyamines, and polythioethers are limited by the use of specific starting materials and lack incorporation of new functional groups, restricting their application in specialty chemical formulations, particularly in personal care products, where new and renewable compositions are desired to enhance performance.
Innovation Solution
A method involving the reaction of compounds with Lewis or Bronsted acids to produce polymers of Formula I, allowing for the use of different starting materials and incorporation of new functional groups, such as olefinic alcohols, which can be derived from renewable resources, and subsequent polymerization techniques like free radical, metathesis, or anionic polymerization to create polymers with enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional polymerization methods are used with specific starting materials, then polymer production is achieved, but the ability to incorporate new functional groups and use renewable resources is limited
Solution Approach 1:
The patent changes the chemical parameters of the starting materials by using olefinic alcohols with terminal double bonds instead of conventional monomers. This parameter change enables the incorporation of renewable functional groups while maintaining polymerization feasibility through the specific reactivity of the terminal double bond position
Solution Approach 2:
The patent creates a universal platform for polymerization that can accommodate multiple types of olefinic alcohols derived from renewable resources. The method universally applies to various starting materials containing terminal double bonds, enabling diverse functional group incorporation across different polymer compositions
2Reliability
If new and renewable compositions are used to improve application performance, then polymer functionality is enhanced, but the complexity of obtaining and processing these materials increases
Solution Approach 1:
The patent performs preliminary action by ensuring the starting olefinic alcohols already contain the desired terminal double bond functionality and renewable functional groups before polymerization. This preliminary preparation of the monomers with the correct structural features simplifies the overall process by eliminating the need for post-polymerization functionalization steps
