Heat curable polymers and a process for making these polymers.

摘要

A process for making a heat-curable polymer comprising the steps of:
<UnorderedLists id="ula01" listStyle="none"><ListItem>(a) preparing a mixture comprising: alkylene-alkyl arcylate copolymer; from 0.1 to 10 parts by weight based on 100 parts by weight of copolymer of difunctional compound having the formula
<Chemistry id="chema01" num="0001"><Image id="ia01" he="6" wi="18" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R<Sub>1</Sub> and R<Sub>3</Sub> are independently selected from the group consisting of -OH,
<Chemistry id="chema02" num="0002"><Image id="ia02" he="8" wi="21" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R<Sub>4</Sub> is C<Sub>1</Sub> to C<Sub>20</Sub> hydrocarbon; R<Sub>2</Sub> is a divalent organic radical terminated with other than aryl;
from 0.1 to 10 parts by weight based on 100 parts by weight of the copolymer of organo titanate;</ListItem><ListItem>(b) heating said mixture to temperature of between the melting temperature of the copolymer and about 200° C.</ListItem></UnorderedLists>
