Document Type and Number:
WIPO Patent Application WO/2018/058816
Kind Code:
A1
Abstract:
The present invention discloses a method for manufacturing a polyoxazoline chain extending agent. The method comprises: using 2-p-hydroxyphenyl-2-oxazoline to perform, under specific conditions, an esterification reaction with a propenoyl chloride so as to produce a propenoic acid monomer comprising an oxazoline group; and inducing carbon-carbon double bond polymerization under specific conditions to produce a macromolecule comprising multiple oxazoline groups. The manufacturing method provided by the present invention can be performed easily, has high yield, and produces a polyoxazoline chain extending agent with high purity and environmental friendliness. The invention has a wide range of prospective applications in the field of chain extension processing for materials such as polyurethanes, polyesters, nylons, and the like.
