## Abstract A new kind of rosinβtype nucleating agent for polypropylene (PP), the cocrystal of dehydroabietic acid, potassium dehydroabietate, and sodium dehydroabietate, was prepared, and the effects of the nucleating agents on the mechanical and crystallization properties of PP were also studied.
## Abstract It is well known that the addition of a small amount of highβpressure lowβdensity polyethylene (HPβLDPE) to linear lowβdensity polyethylene (LLDPE) can improve the optical properties of LLDPE, and LLDPE/HPβLDPE blend is widely applied to various uses in the field of film. The optical ha
