摘要： A synthetic mucin formed by performing a ring-opening polymerization of carbohydrate N-carboxyanhydride (NCA) followed by deprotection of at least one protecting group from the carbohydrate. The resulting synthetic mucin can be produced in large quantities and obviates many of the problems associated with using natural mucins obtained from biological sources.

摘要： The invention relates to a copolymer containing rigid polyamide PA blocks and flexible blocks, characterized in that it includes at least one carboxylic acid chain end blocked with a polycarbodiimide, said copolymer according to the invention being in noncrosslinked linear form. The invention also relates to the use of a polycarbodiimide in a process for manufacturing a copolymer containing rigid polyamide PA blocks and flexible blocks, including at least one carboxylic acid chain end, for improving the extrudability of the copolymer, the drawability of the copolymer, the abrasion resistance, the tear strength and the durability of the copolymer, without increasing its dispersity.

摘要： A recycling process for a polyamide waste material includes the following steps: adding a polyamide waste material into a mixed solvent to obtain a solution, heating the solution to 50° C. to a reflux temperature of the solution, conducting stirring for dissolution, and then conducting decolorization treatment and filtration to obtain a polyamide solution; and adding the polyamide solution into water, precipitating polyamide as a solid in deionized water, and conducting separation to obtain recycled polyamide. The mixed solvent includes, in parts by weight, 10-30 parts of phenol and 15-40 parts of toluene.
