Temperature sensitive polymers and water-dispersible products containing the polymers |
摘要 |
The present invention is directed to a novel process of making N-isopropyl acrylamide (NiPAm) polymers based upon the reaction of poly(acrylic acid) and N-isopropylamine. The disclosed method of the present invention uses polyacrylic acid as a starting material to synthesize NiPAm polymers. In one embodiment, the present invention discloses a condensation reaction of an intermediate salt to form homopolymers, copolymers and terpolymers of N-isopropyl acrylamide (NiPAm) with acrylic acid and/or alkyl acrylates in a molten state, which is adaptable to a continuous reactive extrusion process. Binder compositions, water-dispersible products and thermoformable articles containing the NiPAm polymers are also disclosed.
