A functionalized flame-retardant aconitic acid-derived molecule, a process for forming a flame-retardant polymer, and an article of manufacture comprising a material that contains a functionalized flame-retardant aconitic acid-derived molecule are disclosed. The functionalized flame-retardant aconitic acid-derived molecule can have at least one phosphoryl or phosphonyl moiety with allyl functional groups, epoxy functional groups, propylene carbonate functional groups, or functionalized thioether substituents. The process for forming the flame-retardant polymer can include reacting an aconitic acid derivative with a flame-retardant phosphorus-based molecule to form a functionalized flame-retardant aconitic acid-derived molecule, and combining the functionalized flame-retardant aconitic acid-derived molecule with a polymer. The material in the article of manufacture can be a resin, plastic, polymer, or adhesive, and the article of manufacture can further comprise an electronic component.

The invention relates to a copolymer having polyamide PA blocks and polyether PE blocks, in which PA is of diamine.diacid X.Y type; X, the number of carbons of the diamine, is within the range from 6 to 14, and Y, the number of carbons of the diacid, is within the range from 6 to 18. The invention also relates to the use of the said copolymer in a process of direct adhesion between two TPE materials for increasing the peel strength between these materials.

A polymer film can be adjusted to movement or a fine uneven surface of a living body and has excellent ability to adhere to a biological tissue. The polymer film includes a block copolymer having a structure in which branched polyalkylene glycol and polyhydroxyalkanoic acid are bound to each other, wherein the polymer film has a film thickness of 10 to 1000 nm. The branched polyalkylene glycol has at least three terminal hydroxyl groups per molecule, the mass percentage of the branched polyalkylene glycol relative to the total mass of the block copolymer is 1% to 30%, and a value obtained by dividing the average molecular weight of polyhydroxyalkanoic acid in the block copolymer by X that is the number of terminal hydroxyl groups present per a single molecule of the branched polyalkylene glycol is 10000 to 30000.

The present disclosure relates to polyoxyalkyleneamine (POA) modified sulfonated block copolymers, their preparation and their use as emulsifiers as well as materials for flexible and pressure-adhesive membranes, films and coatings.
