以苯并噁唑脲(
NO
)为催化剂,与杂二环[4.4.0
]
癸-5-烯(MTBD)协同,进行了L-丙交酯的开环聚合以及
δ
-戊内酯与L-丙交酯的开环共聚合,采用核磁共振波谱(
NMR)分析了共聚物的序列结构,原料预混合下所得共聚物的随机度(
R
)为0.5左右,介于完全无规共聚物和嵌段共聚物之间. 采用示差扫描量热分析(DSC)测试了均聚物和共聚物的热性能,共聚物中两单体含量接近时,没有观察到熔融峰的出现,且样品在常温下呈橡胶态,为无定形聚合物;随着戊内酯(VL)链段的减少,共聚物的玻璃化转变温度升高. 嵌段共聚物的分子序列可控,随机度趋近于0.
In combination with 7-methyl-1

7-triazabicyclo[4.4.0
]
dec-5-ene (MTBD)
the benzoxazolyl urea (
NO
) catalyst was very efficient for the solution ring-opening polymerization of L-lactide (L-LA) in the presence of benzyl alcohol. On the basis of homopolymerization
the solution ring-opening copolymerization of L-LA and
δ
-valerolactone (
δ
-VL) was investigated and the PLLA-
co
-PVL random and PLLA-
b
-PVL block copolymers were prepared
via
varying the feeding strategy (premixing or sequential feeding) and the feeding ratio of two monomers. The sequence structure of copolymers was analyzed by
1
H- and
13
C-NMR spectra and the copolymer compositions in the copolymers were in consistence with the feeding ratio of two monomers. The randomness
R
of the random copolymers prepared
via
premixing two monomers was abo
ut 0.5
which was between completely random and block copolymers. The thermal properties were tested by the differential calorimetry scanning (DSC). When the contents of two monomers in the copolymers were relatively close
no melting peak could be observed in the DSC curves and the samples was rubbery at room temperature as an amorphous polymer. As the content of VL segments decreased
the glass transition temperature of random copolymers increased. In addition
the block copolymers (PLLA-
b
-PVL) were synthesized through the "one-pot method" and "chain extension method". The sequence of segments was controllable and the randomness
R
approached zero.
