Novel acid degradable polyacetal polyols and polyacetal polyurethanes able to controlled acid degradation were developed. Polyacetal polyols with various main-chain structures were synthesized by polyaddition of various vinyl ethers with a hydroxyl group 4-hydroxy Bu vinyl ether (CH2=CH-O-CH2CH2CH2CH2-OH), 2-hydroxy Et vinyl ether (CH2=CH-O-CH2CH2-OH), diethylene glycol monovinyl ether (CH2=CH-O-CH2CH2OCH2CH2-OH), and cyclohexanedimethanol monovinyl ether (CH2-CH-O-CH2-C6H10-CH2-OH) with p-toluenesulfonic acid monohydrate (TSAM) as a catalyst in the presence of the corresponding diols 1,4-butanediol, ethylene glycol, diethylene glycol, and 1,4-cyclohexanedimethanol, resp. Polyacetal polyurethanes were prepared by a two-step polymerization, using the synthesized polyacetal polyols, 4,4′-diphenylmethane diisocyanate (MDI), and 1,4-butanediol (BD) as a chain extender. Depending on the main-chain structures, these polyurethanes had different glass transition temperature (from -44 to 19°) and properties such as hydrophobic or hydrophilic. Polyurethanes containing the hydrophilic main-chain exhibited the thermoresponsiveness and had the certain volume phase transition temperature (VPTT). The polyacetal polyurethanes were flexible elastomers around room temperature (∼25°) and thermally stable (Td ≥ 310°) and addnl. exhibited smooth degradation with a treatment of aqueous acid in THF at room temperature to give the corresponding raw material diols. © 2016 Wiley Periodicals, Inc.
