DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23 Me 2-benzylacrylate [3070-71-1] was prepd. by benzylation of di-Me malonate [108-59-8], partial sapon., and decarboxylative methenylation. In polymn. by AIBN in C6H6 at 40-80°, the absence of polymer at 70-80° and the low mol. wt. obtained suggested the existence of a ceiling temp. at 60-70°. Kinetic anal. indicated this ceiling temp. was 67 ± 2° under the conditions used. .

Synthesis and polymerization of trimethyl bicyclobutane-1,2,2-tricarboxylate

Synthesis and polymerization of trimethyl bicyclobutane-1,2,2-tricarboxylate. Hall, H. K., Jr.; Fischer, Walter (Dep. Chem., Univ. Arizona, Tucson, Ariz., USA). Helv. Chim. Acta, 60(6), 1897-902 (English) 1977. CODEN: HCACAV. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Trimethyl bicyclobutane-1,2,2-tricarboxylate (I) [64374-69-2] was prepd. by a 5-step method, beginning with the FeCl3-catalyzed addn. of CHCl3 [67-66-3] to Me acrylate [96-33-3] to give Me 2,4,4-trichlorobutyrate [64374-65-8]. Replacement of the 2-chloro group by iodide was followed by displacement with di-Me malonate [108-59-8] to give tri-Me 4,4-dichlorobutane-1,1,2-tricarboxylate [64374-67-0]. There are some commonly used reagents like 64374-66-9 in this article. Thermolysis of the corresponding Na salt [64374-70-5] gave a 1:10 mixt. of tri-Me cis- [64374-68-1], and trans-3-chlorocyclobutane-1,2,2-tricarboxylate [64374-55-6]. Closure of the bicyclobutane ring to give I was accomplished by KH in ether with MeOH as catalyst. Polymn. of I under free-radical conditions gave moderate yields of homopolymer [64377-16-8] of low-mol. wt., probably due to steric hindrance effects. Copolymn. with vinyl monomers of varying polarity gave moderate yields of low-mol. wt. copolymers consisting mostly of vinyl comonomer units. .
