Poly(butyl methacrylate) is a high-molecular polymer polymerized from butyl methacrylate monomers。 Custom molecular weights are available upon request.
Poly(butyl methacrylate)
Poly(butyl methacrylate)
CAS：9003-63-8
Appearance: Colorless or translucent white powder
Density: 1.06–1.07 g/cm³ (25°C)
Solubility: Soluble in acetone, toluene, chloroform, THF, methyl ethyl ketone and ethyl acetate Insoluble in water, methanol, ethanol and aliphatic alkanes
Comparison with PMMA: Its long alkyl butyl side chains loosen molecular chains, delivering outstanding flexibility, strong adhesion and good low-temperature toughness without brittleness. It features lower hardness, rigidity, light transmittance and solvent resistance compared with PMMA.
Stability: Stable under ambient temperature, excellent weather resistance and resistance to weak acids and weak alkalis. Subject to thermal degradation at high temperatures; hydrophobic with low water absorption.
Storage: Store in a cool, dry and airtight place at room temperature, away from light and moisture.

Coatings & Adhesives
As a homopolymer of soft segment monomer for solvent-based and emulsion acrylic systems, it improves coating flexibility, crack resistance and adhesion to plastics and metals.Widely used in leather finishing, paper coating, flexible wood varnishes, pressure-sensitive adhesives, sealants and ink binders.
Cosmetic Raw Materials
Functions as film-forming agent, skin feel modifier and thickener. Applied in nail polish, color cosmetics and hair styling products; the maximum allowable dosage in nail care products is 6%.
Biomedicine
Drug sustained-release coating for vascular stents: It boasts favorable biocompatibility and low platelet adsorption to prevent stent restenosis.Also applicable to microsphere drug carriers, medical films and embedding medium for electron microscopy specimens.
Polymer Modification & Scientific Research
Standard reference material for GPC (Gel Permeation Chromatography) with multiple molecular weight specifications ranging from 30,000 to 1,800,000
Modify PVC and PMMA via blending or copolymerization to enhance low-temperature toughness
Raw material for optical films, porous polymer membranes and nano-template substrates
