| Popis: | It has been shown that the free-radical polymerization of MMA carried out in the presence of branched PMMAs of various compositions and structures proceeds as a crosslinking process. Branched PMMAs containing reactive C=C bonds serve as weak crosslinking agents; polymers formed in their presence are rarely crosslinked macromolecular structures. The kinetic features of the polymerization of MMA performed in the presence of branched PMMAs and the structure and properties of the polymers are determined by the content of branched PMMAs in the starting monomer-polymer mixture and their structure and physicochemical characteristics. |
