The LAB series bonding agents (modificating of alcohol amine complexing with boron trifluoride),the hydantoin and triazine series bonding agent BA603 and the borate ester bonding agent BAG-5 can effectively raise the mechanical properties of the high-energy four groups HTPB propellant when complexing with MAPO,but they can not meet the require- ments of the engine use.

改性醇胺和三氟化硼的络合物LAB系列键合剂、海因三嗪类键合剂BA603与有机硼酸酯键合剂BAG-5在与MAPO复配用于高能丁羟四组元推进剂中，能有效提高推进剂力学性能，但都不能满足发动机使用要求。

The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.

但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响，当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时，在一般的聚合温度下BF〓不能对它们进行氟化，但可以和其中的OR配位，这种配位进一步加剧了空间位阻，从而阻碍了活性中心的形成，导致催化活性的下降。
