Abstract

The present invention relates to one kind of fluoric super branched-grafted block polymer, and features that the polymer has core-arm structure comprising core of super branched poly(3-ethyl-3-methyol trimethylene oxide) and arm of alkyl substituted amino methacrylate and fluoric methacrylate block polymerized structure. The fluoric super branched-grafted block polymer is prepared through an oxygen ion initiated polymerization process. The fluoric amphiphilic super branched copolymer of the present invention has double temperature and pH responding performance and lowered surface energy, and the preparation process has fast reaction speed, high conversion rate and high product purity.

Description

technical field

[0001] The present invention relates to a copolymer grafted with one or more unsaturated aliphatic group compounds and hyperbranched polyether, each unsaturated aliphatic group has only one carbon-carbon double bond, and only one is based on carboxylic acid ester-terminated; it specifically relates to a "hyperbranched-grafted block" copolymer composed of hyperbranched polyether, (alkyl-substituted amino) methacrylate and fluoromethacrylate, with pH / temperature Responsiveness. Background technique

[0002] Hyperbranched polymers, although the structure is not highly perfect compared with dendrimer polymers, the degree of branching DB<100%, and have a certain degree of molecular weight distribution, but they have similar properties to dendrimers, the synthesis method It is relatively simple and widely used, so it has become one of the research hotspots in the field of polymer science.

[0003] Due to its special properties, stimuli-responsive polymers can ...
