Abstract
Polymer-ceramic networks in which the polymer chain is anchored in a cera network are formed from compounds of the formula ##STR1## where X is R', OR', OH, H, Cl, or Br, X is R', OR', Cl, or Br, R' is an alkyl group having 1 to 8 carbon atoms, and R is selected from the group consisting of phenyl and a phenyl-substituted benzoxazole group, or oligomers thereof. Methods of forming the monomer, oligomer, and polymer are disclosed. Related phthalocyanine polymers are also disclosed.
Claims11
A method for forming a polymer-ceramic network, comprising the steps of:
- a) providing a compound selected from the group consisting of:
- (1) a compound having the formula ##STR22## where R is a benzoxazole group substituted with a phenylene group on the oxazole moiety, such that the fused benzene ring of the benzoxazole group is attached to the C.sub.3 F.sub.6 group and the phenylene group on the oxazole moiety is attached to the --SiXX'.sub.2 group,
- X is OR', OH, H, Cl, or Br,
- X' is OR', Cl, or Br and
- R' is an alkyl group having 1 to 8 carbon atoms;
- and
- (2) a compound having the formula:
- ##STR23## where X, R and R' are as defined above, and
- n is an integer from 1 to about 10;
- b) dissolving said compound in a solvent to form a solution;
- and
- c) adding sufficient water to said solution to hydrolyze and polymerize said compound and thus form said polymer-ceramic network.
A polymer-ceramic network formed by:
- a) providing a compound selected from the group consisting of:
- (1) a compound having the formula ##STR24## where R is a benzoxazole group substituted with a phenylene group on the oxazole moiety, such that the fused benzene ring of the benzoxazole group is attached to the C.sub.3 F.sub.6 group and the phenylene group on the oxazole moiety is attached to the -SiXX'.sub.2 group,
- X is OR', OH, H, Cl, or Br,
- X' is OR', Cl, or Br and
- R' is an alkyl group having 1 to 8 carbon atoms;
- and
- (2) a compound having the formula:
- ##STR25## where X, R and R' are as defined above, and
- n is an integer from 1 to about 10;
- b) dissolving said compound in a solvent to form a solution;
- and
- c) adding sufficient water to said solution to hydrolyze and polymerize said compound and thus form said polymer-ceramic network.
A method for forming a polymer-ceramic network comprising phthalocyanine comprising the steps of:
- (a) providing a compound having the formula ##STR26## where R is ##STR27## and R' is an alkyl group having 1 to 4 carbon atoms;
- and
- (b) adding sufficient water to said solution to hydrolyze and polymerize said compound and thus form said polymer-ceramic network.
