Abstract:
A composition which comprises(1) a matrix material; and (2) a modifying agent which (a) comprises (i) a polymeric moiety which comprises a crystalline polymeric moiety having an onset of melting temperature To and a peak melting temperature Tp such that Tpâˆ’To is less than Tp0.7; and (ii) a catalytic moiety which, when in contact with the matrix material at an elevated temperature, catalyzes a chemical reaction of the matrix material, and (b) is in the form of solid particles which (i) have some of the active chemical moieties on the surface of the particles and the other active chemical moieties hidden within the particles, (ii) are distributed in the matrix material, (iii) have an average particle size of less than 150 micron, and (iv) when heated above Tp, undergo a physical change which (A) substantially increases the extent to which the matrix material is contacted by the catalytic moiety and (B) causes the chemical reaction of the matrix material to take place.
