Abstract
Polymers containing halogen functionality are prepared by the addition or condensation polymerization of at least one halogenated reactant containing at least two active hydrogen-containing functional groups per molecule and at least one halogenated heteroalkyl or halogenated heteroalkenyl group per molecule and at least one co-reactant containing at least two functional groups reactive with the active hydrogen groups of the at least one halogenated reactant.
Claims18
A polymer which is an addition or condensation polymerization product of reactants comprising:
- a) at least one halogenated reactant comprising at least two active hydrogen-containing functional groups and at least one halogenated heteroalkyl or halogenated heteroalkenyl group corresponding to formula (I):
- CX1X2HCX3X4—Y— (I)
- wherein X1, X2X3 and X4 are independently selected from a hydrogen atom, a halogen atom or a halogenated or non-halogenated alkyl group having 1 to 20 carbon atoms, and Y is oxygen (O), sulfur (S) or NR, where R is H or an organic moiety, subject to the proviso that the halogenated heteroalkyl group is comprised of at least one halogen atom;
- and
- b) at least one co-reactant comprising at least two functional groups reactive with the active hydrogen-containing functional groups of the at least one halogenated reactant selected from the group consisting of polyisocyanates, polyisocyanate-functionalized urethane prepolymers, polycarboxylic acids, and epoxy resins.
A method for making a polymer, comprising a step of reacting at least one halogenated reactant comprising at least two active hydrogen-containing functional groups and at least one halogenated heteroalkyl or halogenated heteroalkenyl group corresponding to formula (I):
- CX1X2HCX3X4—Y— (I)
- wherein X1, X2X3 and X4 are independently selected from a hydrogen atom, a halogen atom or a halogenated or non-halogenated alkyl group having 1 to 20 carbon atoms, and Y is oxygen (O), sulfur (S) or NR, where R is H or an organic moiety, subject to the proviso that the halogenated heteroalkyl group is comprised of at least one halogen atom and at least one co-reactant comprising at least two functional groups reactive with the active hydrogen groups of the at least one halogenated reactant selected from the group consisting of polyisocyanates, polyisocyanate-functionalized urethane prepolymers, polycarboxylic acids, and epoxy resins.
