Abstract:
A composition, comprising:(a) a first polymer comprising the repeat units: (i) at least about 10 mole percent of the total repeat units of (ii) at least about 0.1 mole percent of a repeat unit containing a first reactive functional group; (iii) up to about 89.9 mole percent of repeat units derived from one or more monomers which are free radically copolymerizable with (a)(i) and (a)(ii); and (b) about 1 weight percent to about 50 weight percent based on the total weight of (a) and (b), of a second polymer which is elastomeric and contains a second reactive functional group which may react with said first reactive functional group; or (c) a third polymer comprising the repeat units (i) at least about 10 mole percent of the total repeat units of (ii) up to about 90 mole percent of repeat units derived from one or more monomers which are free radically copolymerizable with (b)(i); and (d) about 1 percent by weight to about 60 percent by weight based on the total weight of (c) and (d), of a fourth polymer which is core-shell particles made up of an elastomeric polymer core and a polymeric thermoplastic shell, said thermoplastic shell comprising repeat units derived from methyl methacrylate; wherein: n is 0, 1 or 2; X is â€”Oâ€” or â€”NR9â€”; and R1, R2, R5, R6, R9, each of R3, and each of R4, are independently hydrogen, hydrocarbyl or substituted hydrocarbyl.
