摘要:
The invention relates to a block copolymer which is produced by a controlled radical polymerisation, has an individual composition and structure and is used for adhesion in a humid medium. The inventive copolymer comprises a continuous flexible and water repellent matrix (of elastomer nature) and a dispersed phase in the form of hydrophilic mechanisms. Said copolymer exhibits and excellent adhesion as a result of the structure thereof also is a very humid medium.
摘要:
The invention relates to thermoplastic master batches having at least one copolymer (A) of ethylene and of at least one unsaturated carboxylic acid ester as support and comprising vulcanization agents for rubbers. The invention also relates to a process for the preparation of master batches containing vulcanization agents and having a thermoplastic ethylene copolymer as support, this process consisting in using an extruder.
