A copoly(imide oxetane) having the structure represented by:

• -(G-M)-(D-M)-
• wherein:
• G is represented by the formula
• ═N—R1—C(O)—O-J-C(O)—R1—N═
• wherein:
• J is [CH2—CR2R3—CH2—O]m or
• [(CH2—CR2R3—CH2—O)p—(R6—O)q—(CH2—CR2R3—CH2—O)r] wherein R6 is substituted or unsubstituted aliphatic or aromatic moiety of 2 to 16 carbons;
• R1 is aliphatic or aromatic hydrocarbon moiety of 1 to 10 carbon atoms;
• R2 is —H, —F, or alkyl of 1 to 6 carbon atoms;
• R3 is —F, —R4H(n-a)Fa, —R5—O—R4H(n-a)Fa, and —O—R4H(n-a)Fa, wherein R4 is an alkyl or ether moiety of 1 to 30 carbons, R5 is an alkyl moiety of 1 to 30 carbons, a is an integer of 3 to n, and n is twice the number of carbon atoms in the alkyl moiety plus 1;
• and
• m is between about 4 and 500, p is between about 4 and 150, q is between about 1 and 150, and r is an integer;
• M is represented by the formula
• (—C(O))2-L-(C(O)—)2
• wherein:
• L is a hydrocarbyl-containing moiety of 2 to 100 carbon atoms optionally containing divalent radicals selected from the group consisting of oxygen, silyl, sulfur, carbonyl, sulfonyl, phosphonyl, perfluoro, tertiary amino, and imido;
• D is represented by the formula
• ═N—Z—N═
• wherein:
• Z is a hydrocarbyl-containing moiety of 1 to 100 carbon atoms optionally containing divalent radicals selected from the group consisting of oxygen, sulfur, silyl, carbonyl, sulfonyl, phosphonyl, perfluoro, tertiary amino, and imido.
