  • Preparation of bromine-containing hydroxy-functional copolymers
    Patent number: 6600007
    Abstract: A bromine-containing, hydroxy-functional copolymer is prepared from an initiator that is solid at room temperature and has at least one bromone atom. The initiator is reacted with an effective amount of lactone monomers, optionally in the presence of a catalyst, to establish a bromine-containing, hydroxy-functional copolymer that is a liquid at room temperature. The copolymer of this invention may be used as liquid reactive flame retardant and, in the event the copolymer is polyfunctional, as a crosslinker.
