The structure of products resulting from the free radical copolymerisation of multimethacrylate—poly(vinyl methacrylate)—with acrylic acid was examined by the radiometric method. The copolymerisation was carried out in dilute solutions of N,N ‐dimethylformamide using 2,2′‐azobisisobutyronitrile labelled with 14 C as initiator. The results show that over 90% of methacrylate units react along the template chain forming ladder‐type blocks, while the remaining units branch or do not participate in the process.
