The invention describes compositions that include amine-containing silsesquioxane or an amine-containing alkyltrialkoxysilane and a thermoplastic elastomer as well as methods of preparation of the compositions that are useful as self-bonding adhesives for various substrates.

Thermoplastic compositions include: from about 62 wt % to about 99 wt % poly(methyl methacrylate) (PMMA) or copolymers thereof; and from about 1 wt % to about 38 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. The compositions are scratch resistant. Scratch resistance may be determined as comprising a scratch depth of less than 20 micron (m) as measured in accordance with the Erichsen scratch hardness test at a force of 4 Newton (N). Articles including the thermoplastic composition are also described.

A manufacturing process, which includes: (i) preparing a preform; (ii) laying the preform within a mold; (iii) heating the mold to a predetermined temperature; and (iv) injecting a modified resin system, wherein the modified resin system is formulated to have a viscosity below a threshold viscosity at a specific temperature and a high level of toughness. In one embodiment, the modified resin system contains a combination of epoxies, a curing agent, core-shell rubber particles, a thermoplastic material in an amount of less than 7% by weight, wherein in a cured condition, the thermoplastic material is separated into aggregate domains from the base resin, each aggregate domain having an island-like morphology.
