Abstract:
A mixed acetal derivatized polymer comprising:a polymer having the following monomer units; wherein R is a hydrogen, alkyl alkoxy or acetoxy; R1 is a linear, branched or cyclic alkyl group, a linear, branched or cyclic haloalkyl group, an aralkyl group, or a substituted phenylmethylene having the general structure wherein each R9 and R10 are the same or independently a hydrogen or an alkyl group having 1 to 6 carbons; R2 is a linear, branched or cyclic alkyl group, a linear, branched or cyclic halogenated alkyl group, an aromatic group, or a substituted phenylmethylene having the general structure wherein R9 and R10 are as defined above; R1 and R2 are different from each other; R3 is a hydrogen atom, methyl or ethyl group; or a group having the formula â€”CH2â€”COOR8; R4 and R8 are the same or independently a linear, branched or cyclic alkyl group, a linear, branched or cyclic halogenated alkyl group, an aromatic group or a linear or cyclic &agr;-alkoxyalkyl group; R5 is a valence bond or methylene; R6 and R7 are the same or independently a hydrogen, a linear, branched or cyclic alkyl group, a linear, branched or cyclic haloalkyl group, an aryl group, an aralkyl group, a substituted haloaryl, alkoxyaryl or alkylaryl group, or a combination of R6 and R7 being able to form an alkylene chain, an alkyl substituted alkylene chain, or an oxyalkylene chain; R11 is hydrogen or methyl; 0where all numbers represent mole fractions.
