<p>In a mass polymerization process, substantial improvements, in gloss and/or gloss sensitivity can be achieved by incorporating in the polymerization mixture after the point of phase inversion a specific grafting agent of the formula: R<1>R<2>C=Cr<5>-Cr<6>-Cr<3>R<4> wherein R<1>, R<2>, R<3>, and R<4> are each independently H or Czl to Cz1z5 alkyl, preferably H, R<5> and R<6> are each independently H or a group of the formula: -(CR<7>R<8>)n-CR<9>-CR<1><0>R<1><1> wherein R<7> is H, Cl, Br or I, preferably H, R<8> is H, or a group of the formula -CR<9>-CR<1><0>R<1><1> preferably H Each R<9> independently is H or methyl each R<1><0> and each R<1><1> independently is Cz1 to Cz4 alkyl preferably methyl and n is 1 or 2 provided that R<5> and R<6> are not both hydrogen and preferably R<5> is hydrogen. In a preferred embodiment the grafting is myrcene.</p> |
