摘要:
A block copolymer of the formula hydrocarbon-polyether-polyamide-polyether-hydrocarbon is described. The copolymer may be prepared by reacting together reactants that include dimer acid, diamine, and a polyether having both hydrocarbon termination and termination selected from one of amine, hydroxyl and carboxyl. The copolymer may be combined with a solvent to form a gel, where the gel may be transparent and may be incorporated into household and consumer products including antiperspirants.
摘要:
A low molecular weight, ester-terminated polyamide may be blended with a liquid hydrocarbon to form a transparent composition having gel consistency. The ester-terminated polyamide is prepared by reacting 'x' equivalent of dicarboxylic acid wherein at least 50 % of those equivalents are from polymerized fatty acid, 'y' equivalents of diamine such as ethylene diamine, and 'z' equivalents of monoalcohol having at least 4 carbon atoms. The stoichiometry of the reaction mixture is such that 0.9
摘要:
A low molecular weight, tertiary amide terminated polyamide may be blended with a liquid hydrocarbon to form a transparent composition having gel consistency. The tertiary amide terminated polyamide may be prepared by reacting 'x' equivalents of dicarboxylic acid wherein at least 50 % of those equivalents are from polymerized fatty acid, 'y' equivalents of diamine such as ethylene diamine, and 'z' equivalents of a monofunctional reactant having a secondary amine group as the only reactive functionality. The stoichiometry of the reaction mixture is preferably such that 0.9 ≤ {x/(y+z)} ≤ 1.1 and 0.1 ≤ {z/(y+z)} ≤ 0.7. The gel contains about 5-50 % tertiary amide terminated polyamide, with the remainder preferably being pure hydrocarbon. The gels are useful in formulating personal care products and other articles wherein some degree of gel-like or self-supporting consistency is desired.
