Preparation of carboxyl-containing polymers and composites thereof with hydroxyl-containing materials

摘要

A process for the preparation of carboxyl-containing polymer products which comprises reacting mono- or diolefin homopolymers or copolymers with a low molecular weight thermoplastic copolymer of a carboxyl- containing monomer and an ethylenically unsaturated monomer copolymerizable therewith under the influence of shearing forces. A process for the preparation of composites is also provided which comprises preparing the carboxyl-containing polymer products in the presence of hydroxyl-containing materials.
