Abstract
The present disclosure provides a chlorosulfonated polypropylene carbonate having a structure represented by Formula I, and the production method and use thereof in the fields of binders, stickers, coatings, and others. The present disclosure introduces a highly active chlorosulfonyl group into the molecular chain of polypropylene carbonate, the molecular weight of the final product is decreased at a different degree, and the interface compatibility of the polypropylene carbonate with various substrates can be effectively adjusted and controlled, so that the state and viscosity of the product are modified. At the same time, the chlorosulfonated polypropylene carbonate is also a fully biodegradable material.
