Halogenated advanced epoxy resins

Claim 1

A halogen-containing advanced epoxy resin which results from reacting (A) at least one epoxy resin represented by the following formulas I, II, III, IV, V, VI, VII, VIII, IX or X; and ##STR8## (B) at least one polyhydric phenolic compound represented by the following formulas XI, XII, XIII, XIV, XV, XVI or XVII ##STR9## wherein each A is independently a divalent hydrocarbyl group having from 1 to about 12, carbon atoms, ##STR10## each A' is independently a divalent hydro-carbyl group having from 1 to about 12 carbon atoms; each A" independently is a divalent hydrocarbyl group having from 1 to about 4 carbon atoms; each B is independently represented by the formula ##STR11## each B' is independently represented by the formula ##STR12## each B" is represented by the formula ##STR13## each Q is independently hydrogen or a hydro-carbyl group having from 1 to about 10 carbon atoms; each R is independently hydrogen or an alkyl group having from 1 to about 4 carbon atoms; each R' is independently hydrogen, a hydrocarbyl or hydrocarbyloxy group having from 1 to about 10 carbon atoms or a halogen atom; a has a value of zero or 1; each R" is independently hydrogen, a hydrocarbyl or hydrocarbyloxy group having from about 1 to about 10 carbon atoms, a halogen atom or a glycidyl ether group; each X is independently hydrogen or a halogen atom; each Y independently is hydrogen, a hydrocarbyl or hydrocarbyloxy group having from 1 to about 10 carbon atoms, a halogen atom or a hydroxyl group; each c, c', c" independently has a value from about zero to about 10; m has a value of n-1; m' has a value of n'-1; m" has a value of n"-1; each n, n' and n" independently has a value from zero to about 3; q has a value from zero to about 4; each y independently has an average value from 1 to about 5; y' has an average value of from zero to about 3, each z and z' independently has a value from zero to about 3; and wherein (i) at least one of components (A) and (B) contains at least one halogen atom which is in the meta position with respect to an oxygen atom attached to the ring for each two aromatic rings; (ii) when the average epoxide functionality of component (A) is not greater than 2 and the average hydroxyl functionality of component (B) is not greater than 2, components (A) and (B) are present in quantities which provide a hydroxyl to epoxide ratio of from about 0.1:1 to about 0.9:1; (iii) when one of components (A) and (B) has an average functionality of greater than 2 and the other has an average functionality of not greater than 2, components (A) and (B) are present in quantities which provide a hydroxyl to epoxide ratio of from about 0.01:1 to about 0.4:1; and when both components (A) and (B) have an average functionality of greater than 2, components (A) and (B) are present in quantities which provide a hydroxyl to epoxide ratio of from about 0.01:1 to about 0.3:1.
