poly(methacrylic acid)
polymerPoly(methacrylic acid) is a synthetic polymer featuring pendant carboxylic acid groups along its backbone, giving it strong hydrophilic character and pH-responsive behavior. It is widely used in pharmaceutical delivery systems, adhesives, coatings, and water-treatment applications where its ability to absorb moisture, form hydrogen bonds, and respond to pH changes is valuable. Engineers select this polymer when seeking biocompatible, chemically reactive matrices for controlled-release formulations or superabsorbent materials, though its thermal stability and mechanical strength are generally lower than commodity polymers, limiting load-bearing structural applications.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
