Synthesis and thermal behavior of chloroacrylate-vinyltriacetoxysilane copolymers. Rao, V. Lakshmana; Babu, G. N. (Dep. Chem., Indian Inst. Technol., Bombay, India). Polym. Prepr. (Am. Chem. Soc., Div. Polym. Chem.), 24(1), 127-8 (English) 1983. CODEN: ACPPAY. ISSN: 0032-3934. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23 Vinyltriacetoxysilane (I) [4130-08-9] was polymd. with 2-chloroethyl methacrylate (II) [1888-94-4], 2,2,2-trichloroethyl methacrylate (III) [50601-47-3], and methyl a-chloroacrylate (IV) [80-63-7] in bulk in presence of AIBN initiator at 60° and the reactivities and polymer properties were detd. The reactivity ratios for I indicated that it did not undergo self propagation. The reactivity of I toward the polyacrylate radicals was: I > III > IV. The soly. of the copolymers in various org. solvents was the same as those of the acrylate homopolymers but changed significantly upon exposure to air. Mol. wt.There are some commonly used reagents with their cas registry numbers 89989-14-0 and 1888-94-4 in this article. decreased with increases in silane content in the copolymer. The copolymers had broader mol. wt. distributions than the corresponding homopolymers. The copolymers showed higher glass transition temps. than the polychloroacrylates. Thermogravimetry of I-III copolymer [89989-14-0] and I-IV copolymer [89989-15-1] showed 2-stage wt. losses whereas I-II copolymer [89989-16-2] exhibited a single-stage wt. loss. .

Spontaneous polymerization of methyl methacrylate

Spontaneous polymerization of methyl methacrylate. 8. Polymerization kinetics of acrylates containing chlorine atoms. Lingnau, J.; Meyerhoff, G. (Inst. Phys. Chem., Univ. Mainz, Mainz D-6500, Fed. Rep. Ger.). Macromolecules, 17(4), 941-5 (English) 1984. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Me a-chloroacrylate [80-63-7] and b-chloroethyl methacrylate [1888-94-4] polymerize spontaneously at much higher polymn. rates than Me methacrylate [80-62-6].In this experiment, several chemicals are used like 97-63-2 and 80-63-7 The results are interpreted in terms of an intramol. catalysis of the intersystem crossing reaction of the intermediate biradical by the Cl atom. .
