Propylene glycol monomethyl ether (PM) is a member of the family of glycol ether with a wide variety of consumer products and industrial applications.
PGM is used in the chemical, agricultural, automotive,paint, lacquer, and varnish industry.
Propylene glycol methyl predominant use is as a solvent in various manufacturing processes and as a chemical building block for the manufacture of propylene glycol methyl ether acetate.
PGM is produced commercially by reacting propylene oxide (PO) with methanol in the presence of catalyst.
Due to the asymmetry of propylene oxide, the epoxide ring of propylene oxide may open either at the C–O bonds, so that the eaction yields a mixture of two isomers with the a-isomer, 1-methoxy-2-propanol (PPM) and the b-isomer, 2-methoxy-1-propanol.
Among the products, PPM has a lower toxicity than 2-methoxy-1-propanol, so high selectivity is required for the reaction.
Acid catalysts, such as BF3, heteropolyacids and solid acids, can be used for the reaction and appear to exhibit good catalytic activity, but they inevitably produce undesirable 2-methoxy-1-propanol and other byproducts.
The epoxy ring of PO may preferentially open at the least sterically hindered position over the basic catalyst and lead to most secondary alcohol PPM.
Homogenous base catalysts such as sodium methoxide and NaOH, how high activity and selectivity, but they suffer from the drawbacks of separation, liquid waste treatment and corrosion.
The replacement of currently used homogeneous alkaline
catalysts by solid catalysts can result in catalyst reuse and waste stream reduction and make the process of industrial production environmentally benign and economical because of their non-corrosiveness and easy separation from products.
Thermo-responsive polymers (temperature-responsive polymers) are polymers that respond to temperature.
When aqueous solvents are present, the response is seen as a change in the hydrophilicity of the structure.
Propylene glycol methyl the hydrophilicity, and thus the water solubility, increases or decreases when the solution is heated, the polymers are characterised by either an upper critical or lower critical solution temperature, UCST or LCST, respectively.
LSCT polymers have attracted much scientific interest for potential in biological applications, as they are soluble at low temperatures, at which they can be easily mixed with drugs and cells, without compromising their structural integrity.
Propylene glycol methyl the appropriate external conditions, solvent, pH and temperature, depending on the molecular structure, the incompatibility with the solvent can be manifest by the formation of a 3D physical network.
Propylene glycol methyl networks are known as thermoresponsive gels (TRGs) and find numerous applications in biomedical engineering as injectable gels for tissue engineering and drug delivery, and 3D printing.
One of the most extensively studied families of thermoresponsive polymers are poloxamers, i.e. ABA triblock copolymers with A and B blocks being based on ethylene glycol (EG) and propylene glycol (PG), respectively.
Whilst poly(ethylene glycol) (PEG) is highly hydrophilic and thermoresponsive at high temperatures depending on its molar mass (MM),16,17 poly(propylene glycol) (PPG) is thermoresponsive at lower temperatures.
Propylene glycol methyl specifically, PPG is hydrophilic below room temperature, depending on the concentration, whilst it is hydrophobic at higher temperatures, thus promoting self-assembly.
Various poloxamers are commercially available with differences in the EG/PG ratio and the total MM.
Propylene glycol methyl polymer has a total MM of approximately 12 600 g mol−1, and a composition of EG-PG = 70–30 w/w%.
Propylene glycol methyl aqueous solutions form gels at a concentration of at least 15 w/w%, with gels being formed at room temperature at only 20 w/w%.
Owing to its commercial availability and interesting thermogelling properties, many studies have been focused on applying it either as in vivo injectable gel and as 3D printable material.
As PEG is highly hydrophilic and largely biocompatible, it has often been incorporated into biological systems to enhance biocompatibility.
(Meth)acrylate derivatives of PEG are commercially available and have gained significant scientific interest in the last two decades.
When polymerised, the backbone of the polymer consists of carbon–carbon bonds, with the ether bonds (originating from the EG units) being on the side chain, and their thermoresponsive ability is affected by the number of EG repeating units.
Poloxamers contain both EG and PG repeating units in a linear polymer consisting of ether bonds along the backbone.
Using (meth)acrylate PEG and PPG derivatives is advantageous as a wider variety of monomers can be used, including functional groups at which peptides or fluorescent groups might be attached post-polymerisation.
Propylene glycol methyl addition, these functional monomers could be polymerised at different points within the polymer chain with appropriate polymerisation methodology, unlike in poloxamers, in which the functionalisation can only take place at the ends of the polymer chain.

Propylene glycol monomethyl ether epoxide ring of PO might open at either of the C-O bonds to form primaryor secondary alcohols.
Compared to secondary alcohol, the primary alcohol (such as2-methoxy-1-propanol) has a much greater toxicity.
Therefore, high selectivity to the secondary alcohol is preferred for this process.
Propylene glycol monomethyl ether ring of PO might preferentiallyopen at the least-sterically-hindered position over a basic catalyst, leading to the pre-dominant production of secondary alcohol 1-methoxy-2-propanol.
