23 Jul Method for preparing annular aliphatic carbonic ester containing cinnamoyloxy group and polymers thereof
Abstract
The invention relates to a preparing method of cyclic aliphatic carbonic acid esters containing cinnamoxyl, and polymers thereof, belongs to the biomedicine high-molecular material field. Aliphatic cyclic carbonic acid ester 2-methyl-2-cinnamoxymethyl cyclictrimethy carbonic acid ester and 2-ethyl-2-cinnamoxymethyl cyclictrimethy carbonic acid ester are synthesized from 2, 2-dimethylol optal and 2, 2-dimethylol butanol, further homopolymers of the same, copolymers with aliphatic cyclic ester, block copolymers with carbowax, and block copolymers of random copolymers with aliphatic cyclic ester and carbowax are synthesized. The copolymers contains cinnamoxyl pleurocoxal capable of generating reversible cross bonding reaction. With the biodegradability of the bioavailability, the copolymers can be used as biomedicine materials useful in fields, such as surgicals, medicine controlled releasing, tissue engineering, etc.
