英文摘要A kind of beta-nucleating agent, namely a stearic acid and stearate lanthanum complex (na beta), was introduced into isotactic polypropylene (i-pp) via an in situ polymerization method for the first time. a dynamic adhesion model was constructed for interpreting the beta-nucleating agent dispersion process. the effects of a polymerized dispersion of the beta-nucleating agent on the content of beta-crystal and crystallization behavior of i-pp were investigated. the results show that the crystallization peak temperature of thus beta-nucleated i-pp was greatly increased while the spherulite size dramatically decreased compared with those of net i-pr the content of beta-phase (k(beta) value) can reach as high as 88.7% with only 0.135 wt% of na beta addition, which holds constant with a further increase of na beta concentration up to 3.41 wt%. the non-isothermal crystallization kinetics of thus beta-nucleated i-pp was studied with mo equation and crystallization activation energy estimated by kissinger method, giving unique results pertaining to the unprecedented nap polymerized dispersion.
