FRICTION-ACTIVATED ADHESIVE FORMULATIONS AND APPLICATION DEVICES

摘要

A solid thermoplastic semi-crystalline friction-activated adhesive composition comprising the mixture of: (a) from about 50 to about 100 parts by weight of a semi-crystalline adhesive polymer that comprises: (1) crystalline monomer having an alkyl carbon length of at least 16 carbon atoms; (2) non-crystalline monomer having a homopolymer Tg below about 80° C.; (3) waxy, soft monomer having an average pendant alkyl carbon length of at least 14 carbon atoms; (4) monomer having acid or base functionality; (5) functional or non-functional macromere having a Tm from about 40 to about 120° C.; (b) 0 to about 50 parts by weight of tackifier; (c) 0 to about 50 parts by weight of crystalline additive; (d) 0 to about 50 parts by weight of filler; (e) 0 to about 30 parts by weight of oil; and (f) 0 to about 50 parts by weight of one surfactant. Also glue crayons and other application devices comprising such adhesive compositions.
