N-hydroxymethylacrylamide bụ ntụ ntụ ọcha kristal. Njupụta ya bụ 1.185 (23/4 ℃), ebe agbazekwa bụ 75 ℃. N'ozuzu, enwere ike ịgbaze ihe mgbaze hydrophilic, maka abụba acid esters, acrylic acid na methylacrylate, ikpo ọkụ nwekwara nnukwu mgbaze, mana ọ fọrọ nke nta ka ọ ghara ịgbaze na ihe mgbaze hydrophobic dị ka hydrocarbons, halogenated hydrocarbons. Enwere ike iji ya dị ka ihe na-ejikọ cross-link, nke a na-ejikarị eme ihe na fiber modified resin, nhazi agba, plastik binder, ala stabilizer, wdg. molekul nke ngwaahịa a nwere njikọ abụọ ejikọtara ya na otu carbonyl na otu reactive hydroxyl methyl. Ọ bụ monomer njikọta cross-linked nke a na-ejikarị eme mgbanwe eriri, nhazi resin, ihe nrapado, akwụkwọ, akpụkpọ anụ, ihe na-agwọ elu ígwè, a pụkwara iji ya dị ka mgbanwe ala.

Ọ bụ ihe e ji emepụta resin thermosetting, mkpuchi epoxy resin nke na-agbanwe agbanwe, mkpuchi na-anaghị ekwe mmanụ na mkpuchi nkụ. A na-eji emulsion copolymerization ya eme ihe maka imecha eriri, ákwà, akpụkpọ anụ na akwụkwọ. A na-ejikwa ya dị ka ihe na-arapara osisi, ígwè, wdg.
A na-eji ya dị ka monomer jikọtara ọnụ maka acrylic emulsion. Ọnụọgụ nke acrylic emulsion pressure sensitive gluu nke nwere carboxyl group bụ L% ~ 2% nke mkpokọta monomer mass, ọ bụrụ na ọ karịrị 3%, viscosity mbụ ga-ebelata nke ukwuu. Maka ihe mgbakwunye emulsion na-enweghị otu carboxyl, usoro ọgwụgwọ izugbe erughị 5%. Okpomọkụ mmeghachi omume crosslinking MMAM naanị dị elu, n'ozuzu ya bụ 120 ~ 170℃, itinye ihe mkpali ụdị proton nwere ike ibelata okpomọkụ crosslinking. Acrylic acid (AA) nwere ike inye hydrogen protons, copolymerization na acrylate, yabụ MMAM iji mepụta ihe nnọchi anya crosslinking composite na AA, ọnụọgụ nke 3:2 ka mma. cross-linker HA nwere ike dochie N-hydroxymethylacrylamide ma ọ nweghị formaldehyde.
