Cyclic acetal-photosensitized polymerization: Cyclic acetal-photosensitized polymerization. VI. Photopolymerization of 2-vinyl-1,3-dioxolane. Ouchi, Tatsuro; Nakamura, Takaki; Oiwa, Masayoshi (Fac. Eng., Kansai Univ., Suita, Japan). J. Macromol. Sci., Chem., A11(9), 1651-62 (English) 1977. CODEN: JMCHBD. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) A radical mechanism is proposed for the photopolymn. of 2-vinyl-1,3-dioxolane (I) [3984-22-3], which was conducted at 40° in C6H6 without the usual radical initiator. I is decompd. by photoirradn. to a cyclic acetal radical which is instantly converted to the ester radical via b-scission of the dioxolane ring; the vinyl polymn. is probably initiated by the ester radical. Kinetic data show the initiating radical and the propagating radical readily abstr. the H between the 2 alkoxy groups in I as a radical. Because of the degrative chain transfer by an allylidene group, the rate of polymn. and polymer mol. wt. are very low.
