Ed., 22(5), 249-54 (English) 1984. CODEN: JPYBAN. ISSN: 0360-6384. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23, 25 N-Methylformamide [123-39-7] was treated with p-chloromethylstyrene [1592-20-7] to give N-methyl-N-(p-vinylbenzyl)formamide (I) [90499-42-6], which was homopolymd. and copolymd. with styrene (II) to give I polymers [90505-83-2] and I-II copolymer [90505-84-3], useful as phase-transfer catalysts for the reaction of alkyl bromides with nucleophiles. The catalytic activity of I-II copolymer increased with increasing II content. The reactivity ratios and Q-e values for the polymn. of II with I were given.

Functional polymers and sequential copolymers by phase transfer catalysis. 12. Functional polymers containing 2-(p-phenoxy)-2-oxazoline pendant groups. Percec, V.; Nava, H.; Rodriguez-Parada, J. M. (Dep. Macromol. Sci., Case West. Reserve Univ., Cleveland, OH 44106, USA). Polym. Bull. (Berlin), 12(3), 261-8 (English) 1984. CODEN: POBUDR. ISSN: 0170-0839. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Two methods for prepg. functional polymers contg. 2-oxazoline pendant groups are presented. The 1st consists of the phase transfer-catalyzed etherification of 2-(p-hydroxyphenyl)-2-oxazoline (I) [81428-58-2] with m- [39833-65-3] and p-(chloromethyl)styrene [1592-20-7] to give m- [94099-19-1] and p-vinylbenzyl ethers [94060-31-8] of I. Radical polymn. gave a polymer [94060-32-9] contg. oxazoline pendant groups. The 2nd method was phase transfer-catalyzed etherification of poly(2,6-dimethyl-1,4-phenylene oxide) contg. pendant CH2Br groups with I. Incomplete etherification of bromobenzyl groups gave a polymer contg. cationically polymerizable heterocycles and their own cationic initiator as pendant groups.
