| abstract | 1,238,388. Process for grafting olefin polymers. AVISUN CORP. 5 Dec., 1969 [5 Dec., 1968], No. 59489/69. Heading C3G. An ethylenically unsaturated monomer is grafted on to an olefin polymer using a free radical initiator which is a perester selected from t-butyl 2-ethylperhexanoate, t-amyl 2- ethylperhexanoate, t - butyl - 3,5,5 - trimethylperhexanoate, t-amyl 3,5,5-trimethylperhexanoate, t-butyl 2-ethylperbutyrate, t-amyl 2-ethylperbutyrate, t-butyl perisobutyrate and t-amyl perisobutyrate. The monomer is preferably a nitrogen-containing heterocyclic monomer, e.g. a vinyl pyridine, vinyl morpholinone or vinyl lactam, or a mixture thereof with another monomer. In examples, the graft polymerization is carried out in aqueous suspension, the olefin polymer and graft monomers being as follows: (a) polypropylene, 4-vinylpyridine or 2-methyl-5-vinyl pyridine, and styrene; (b) polypropylene, N-vinyl-2-pyrrolidone and methyl acrylate; (c) polypropylene, 2-methyl-5-vinyl pyridine, and 4-vinylpyridine and (d) propylene-ethylene terminal block copolymer, 4-vinylpyridine and styrene. Fibres produced from polypropylene grafted with 4-vinylpyridine and styrene are dyed. |
