Abstract

Abstract2‐Chloroethyl 2‐(methacryloyloxy)ethyl hydrogen phosphate (5a) and 2‐bromoethyl 2‐(methacryloyloxy)ethyl hydrogen phosphate (5b) were synthesized, characterized, and polymerized with 2,2′‐azoisobutyronitrile (AIBN). In the polymerization of 5a in DMF with AIBN, the rate of polymerization was found to be proportional to [AlBN]0,54 and to [5a]1,54. The over‐all activation energy for the polymerization of 5a was estimated as 59,5 kJ · mol‐1. From the radical copolymerization of 5a with styrene in DMF at 60°C, Q and e values for 5a were evaluated as Q = 2,65 and e = 0,53.
